Uncle Bird - Thanks for the observation, I never realized my heels came up like that.
Missdibs - Thanks for all the links, I'll definitely be checking them out.
Fleming13 - Thanks! I'll give that a shot next week.
Javiercarlin - Very, very helpful! Thank you very much! So to avoid the "butt wink" should I try to keep from going so deep until I have gained the mobility to do so?
Thanks again for all the help everyone!
