Bow companies continue to raise the Bar every year so it really doesn't matter when you buy a Bow a year later you may wish you had waited. I have got a new bow every year for as long as I can remember.
One reason I sell my bow almost every year isI can get a good price for my year old bow and it doesn't cost me a ton to trade up.
I owned an 05, 06, & 07 Allegiance they made improvements every year but the 05 was still a Great bow
