Just wondering peoples opinions and reasoning behind which rotation to use for a hit and roll.

I was always told that if you wanted to minimize the roll you should use the turn that curls towards the rock you are hitting.
eg. rock two feet to the right side of center and you want to roll a couple feet behind a tight center line guard (looking from throwing end) use in turn.

If you want to roll further you would use the other turn.
eg. rock top twelve right hand wing and you want to roll behind a guard on or left of center use out turn.

There are of course times when you don't get a choice in turns due to the position of rocks in play. Sometimes it is also better to play the turn you thrown the most in the game and know how it is going to curl versus trying a brand new turn. That's my two cents.

Outside - in is usually easier to read and less awkward to throw I find. Across the face is usually the better way to get the roll because there is not as much spin imparted on the rock on contact.

All things being equal, better roll is curling into the rock (which usually ends up being inside-out) as it has more action - something Russ Howard says all the time. However, the shot should be dictated by a number of other factors - 1) your preferred handle, 2) your preferred line of delivery - some find inside-out difficult compared to outside in (ie. sliding close to center line can be tough), 3) which way you know the ice more.

If you hit on the high side (the direction from which the stone is curling) the stone spin works with the momentum of the recoiling stone to give you a more lively (faster) roll and a little farther back that you would expect from the contact point. If you cross over and hit the low side, the spin of the shooter will reverse after contact and this will kill the recoil momentum, resulting in a flatter, deader roll. (That conservation of momentum thing--you know, the stuff you slept through in physics-some of the stone momentum is transferred to angular momentum when the stone reverses rotation. But we digress into academics...)

Which turn to throw is more often is dictated by the required path to the target stone (e.g. navigating around guards) rather than the live or dead roll. Especially on club ice, the outside-in hit will often run straighter than the inside-out and is easier to ice and control with sweeping. However, when playing in-offs or cross-house doubles, the live roll is often preferred to get enough "action" to roll the rock far across the house.

Cheers.

Thanks all for the replies! It is just as I thought, everyone has slightly different opinions and sound reasoning behind them. I'm just as confused as ever!

Cheers!

An outdated or poorly designed bathroom can be frustrating to use. Upgrading your bathroom can improve the functionality of the space, making it more efficient and enjoyable to use. This could include adding more storage, creating a more open layout, or installing new fixtures that conserve water. cabinet makers rochester mn
