Just a few random questions

I figured compling my random questions into one post was better than two or three. 1. When I breath to my left before I do a flip turn then I can't do a good one. I end up rolling sideways, like over my shoulder, rather than front, tucking my head and going. I've tried looking to the left and then rolling in the middle of the pool and the same thing happens. I just can't seem to get my head back to being straight before I roll. Any ideas of how to fix this other than just breath to the right because sometimes my stroke count doesn't work out so that I can do that all the time? 2. This new backstroke rule...Im still kinda confused. So when I roll onto my stomach then I have to either roll immediately or take a stroke that is part of the continous roll motion right? I can't glide to the wall? 3. How can I improve my lung capacity? I need to be able to hold my breath longer so that my underwater kicks can take me as far as I know they can and not be hindered by a need for air. I think that was everything for now. Thanx for all your help!! ~Kyra
