As for the draw length, the same thing happened to me a couple years back. When bought my 02 Magna Tec, my draw length went from 30 down to 28.5. I didnt even think about it when I bought it. I purchased by bow online as well. I was so lucky that it didnt drop anymore, because the bow was adjustable from 28.5 to 31. Another .5 lower and I would have been one PO'd archer.

Good Luck with the new bow!
