RE: Which would you choose?
The infamous Bowtech Limb problem was largely misinformation disseminated on Archery Talk and other forums. Do a search on this board for Archery Talk and you'll find the notice that they posted regarding brand bashing.
This largely came about as a result of certain individuals on a smear campaign.
Personally, I went with the SB over the Trykon. Smoother to draw and smoother to shoot. Those were my #1 and #2 criteria.
