My draw stop was in the same place as purchase like you Polaris. I changed strings on my Firecat a month ago and didn't really have the back wall that I thought I should have. I moved the stop back a little (1/8"), which helped. I haven't noticed any ill effects by doing so and still flinging arrow pretty quick (don't have a chron). Good luck with what you decide.
