Like everyone else has said if you like the bow shoot it and hunt with it. When I started shooting I thought I needed a new bow all the time. I always bought used or discontinued because I just couldn't stomach the new prices. I started with a used mathews switchback xt then I got a used '08 hoyt pro elite for indoor league. I finally got a discontinued '08 Hoyt Katera XL that I picked up in 2010 and have been hunting with since then. I have zero desire for a new bow. Heck it took me 2 years to get a deer with the "new" bow. I still like it and plan to continue to use it. Just the other day I finally sold my pro elite since I dont do much shooting for indoor leagues these days. I plan to use my katera again next year and probably the year after that. I dont know what would make me get a new bow but I haven't found much compelling new technology that I "need". I have a 27" draw and I get plenty of speed out of this old bow that the deer I have shot with this bow from 15-35 yards with a mechanical bh haven't gone more than 40-50 yards and all have have partial or complete pass threws. The drenalin is a good bow.

I do at times get the urge to replace my bow maybe get something with a shorter ATA since 35" is a pain in my summit climber at times but I just cant justify it since now I hunt mostly out of ladder stands where it is a non issue.

Plus with the cost of a new bow which has a depreciation like a new freaking car it is hard to justify. Especially for me when you can get a new high quality rifle for the same price or less and the gun will have a much better resale value especially in 5-10 years .
