Surely the reason we have straight playing conditions pretty much everywhere is not becuase we like it that way!?

I have never come across ice that I would consider curls too much.


This has always been a problem, throughout the curling world. During the preparation of Curling Ice Explained all the experts were consulted in order to find the consensus and from that the following was used as the specific definition of curling ice by the WCF:

"To play an offensive game with many stones in play, the curl with naturally-matured stones (see above) should be 4 foot on a draw – not less and not more. This will allow for draws around a guard stone with adequate distance between the guard and hidden stone. It is possible with good precision to play a “freeze”, and even to be able to push a hidden stone."

"To have the same speed and curl in the beginning of a game as at the end is important, because the teams can begin the offensive play immediately without risking too much. A good draw weight should be 24-25 seconds (hog to tee) all over the sheet from the first end to the last on both the in-turn and out-turn. There should also be good “living” in the stone, which means that the stone shouldn’t slow down too fast at the end of the movement and should be easy to sweep."


From an ice technician's point of view, we need to know what we're trying to achieve when we make the ice. From a player's point of view, you tell me what you want and we can argue about it here!

Aye - I think that's about right.  The 4 feet - not less not more sounds a tad prescriptive, does it not Grin?  Too much of a draw though and guards are almost useless unless they are tight, tight, tight to the house.  In effect, you are taking out of play the long guard - indeed al of the space between the hogline and very near the house.

If all ice was exactly as described there, would that not take away part of the challenge of the game?

Admittedly, pro footballers don't expect the playing fields to be vastly different, but is that not part of the appeal or allure of curling?

I believe the final question regarding the amount of draw and consistency is down to the choice between testing a player's skill at delivering a stone accurately, or a player's ability to read changing conditions. With the latter local advantage comes into play which, to all visiting players, is not fair.
I must add that a competent curling-ice technician should be able to achieve the definition under just about any circumstance. There are many who can't, of course, but that's what has become the norm at all serious competitions in Canada and Europe. My own experience with club curlers is that they thrive on the definition but struggle if the specifications change.

123 members indeed! Great! Now for the next 123....

I think, when Perth is at its best, with about 5 feet of curl and a tee to hog split of 3.1 secs.
What is 24-25 secs in tee hog form?

In all the World, European and Olympic Championships, as well as the slams out in Cananda, they have a lot more curl than 4ft usually.

It is a strange world indeed and VERY complicated, but no, I don't have all the answers. However, we're working on it harder than ever! I said years ago that the players will learn about good ice and start playing better and better, which will force ice techs and venues to make better ice -- or lose. The margins are very small now and becoming smaller all the time.
The report on Friction v Temperature is finished, I'm just waiting on my colleagues to check the details before I publish it. Meanwhile be sure to read the one below, it makes a start!

i thought it was the other way round for the districts.

but i think they were only cutting the ice every second draw so the same sections got the second session for a weekend then it swapped.

You'd be surprised.  You often here the Canadians complaining about the ice at the slams. I watched a bit of the last slam on CurlTV and the ice was stiff and straight.

What about the worlds at Paisley?

I know you said usually!

I have never played in any canadian bonspiels but i have at several european championships and a worlds and the ice has been pretty straight.....      not that i am complaining..... i think 2 feet curl is perfect at draw weight
i think that these new "aggresive" running bands could turn curling into circus event.    The few times i have used them they are fine until the pebble wears down  (6th end at most places) and then they really dive.  I was playing with these stones recently and was able to hit and lie at strike weight a stone in 4 foot completely guarded by a stone about 6 feet short of house....  that cant be right!!

Aye - I think four feet draws at strike weight (and you don't normally hang back!) is extreme and I agree that that kind of thing is more Barnum's than anything else.

Ice that is too straight though tends to flatter the poorer curler.  Ice on the edge of the stone and "wham, bang, thank you ma'am" lacked subtlety - though it is what we were brought up with, I know (unless, like me, you learnt to curl at Crossmyloof!!).

The happy medium - four or five foot consistent draws across the sheet is what we should be aiming at in my view.  I have never curled in any of the top-flight Canadian bonspiels, but did play in 31 different rinks on the tour in 2003.  Ice was consistently good, as I have remarked on the board before.

Funnily enough, I am not so much of a fan of the lightning keen ice that you find in some venues now.  I prefer ice with a bit of a stiffness about it - 2.7 to 2.8 tee line to hog.  You've actually got to "throw" the stone, as opposed to sliding out the hack and just letting it go, if you see what I mean.

Each to their own, I suppose.  Each to their own.

Yeah it would have been like that for you. You were in either section A or B and got the freshly cut session. Giving you 3.1 split and 5ft curl for the first weekend. Which we got in the second weekend becuase group C and D were getting the freshly cut ice.
