Shooting, passing and just moving the puck in general are much easier on the ice, after you get the skating back the rest is easy, although offsides and icing are a little tough mentally to get through sometimes.
i went from roller to ice- and the transition is much easier than many think. here are some tips that helped me:
- a high lo chassis mimicks an ice boot very well. continue with this setup.
- i highly recommend general ice skate sessions as much as possible. learning to stop on both sides might take a little while. on ice you can do everything a little bit quicker- ESPECIALLY stopping.
- you have to really carve into those strides to move on ice....this will make your roller hockey stride more powerful as well.
-your stick should transfer over well. the main difference on ice is that instead of "pushing" the puck on a high friction floor surface...you basically have to skate to follow the speed of the puck on ice. it really moves just by tapping it lightly. i find puck handling/ shooting on ice MUCH easier...
good luck and let me know if you have anymore questions!
