What swimming stroke do you prefer?
Back stroke is my favorite 
Back stroke is always challenging during the flip turn. Have you got that mastered yet?
I've been working on it but sometimes I still get a bump to the head
Does the pool you swim at have flags? Some people count the strokes from the flags. 
That is a great tip, there are no flags, but there is a ladder I could use a marking point.
Keeping the body streamlined seems to help your backstroke. Is this something you have had to work on?
I've been focusing on getting my kick movements down, i'll have to work on streamlining 
Maybe once you get the kick down you will be the next Aaron Peirsol. Do you follow competitive swimming?
I try and catch some of the swimming on the olympics but overall I do not follow the competitive swimming world.
