I ordered a Jaguar from a dealer at 50#. The info section said that the draw weight was adjustable. I have a 31# draw length and i was wondering if i should step down to a 40#. With a 40# I'll be holding 46#; with a 50#, 56#. If I can dial the 50# back to 40# I'll have more versatility. I plan to hunt deer with this bow and I want to be sure I have enough poundage to get good penetration AND fairly flat trajectory. Is the Jaguar adjustable amd how is it done?
