I'm still shooting the same bowtech since 2004.....no issues at all. I shoot about 6-7 grains per pound.
I'll be looking at a BT Prodigy soon to see how it shoots.
I shot an Addy for 5 years and didn't have a minutes trouble from it.....wish I still had it. Full disclosure: I have a Prodigy now and it's the smoothest (3 setting) vib free bow I've ever shot. But....,I did have a limb split and got them all replaced for $50. Not a problem since and I'm just now getting my confidence back in it as far as durability.
