Deep end flip turn vs shallow?

Hi all, I noticed something this past week on my flip turns. I consistently get a smoother, faster turn at the deep end of the pool, and my shallow end turns are less fluid and a bit more timid coming into the wall. I assume this is because the shallow depth makes me feel a bit more crowded so that I hesitate more. Also I think I tuck my legs in more at the shallow end and my timing is slightly off. Any suggestions?
