Yep. The more anchor references you can build into your form, the more consistent shooter you will be. So I also think they're steering you in the right direction.
I've lost 2" of draw length by going from high wrist to low wrist, fingers to release/loop. But, I could afford it and I'm actually better off for doing it. They don't make many 34" draw bows these days.<img src=icon_smile_wink.gif border=0 align=middle>
Don't worry about the drop in draw length. Using the bows we shot 20 years ago as a baseline, you'll be shooting faster arrows with these new fangled bows at 29" than you ever did at 31.5.
