Thanks for all the input, you all. You helped a lot with the decision.
I think in Hawaii "Big Boar" means a slightly more demure thing than on the continent. With my M330 at 30 yards, using stock Diablos and Boltcutters, bolts go right through. They will even travel quite a good distance lengthwise to reach the exit, sometimes. I do agree, however, that going lighter and using mechanicals would be a mistake.
So, after a good deal of hemming and hawing, cogitating and scratching my head, I had an epiphany: I like crossbows for crossbows' sake. I don't NEED another one, but do I really need to do such gymnastics to justify WANTING and HAVING another one? No. After all this, I realized that the Micro 335 was the Goldilocks choice of the bunch for me, in terms of cost, draw weight, effectiveness and being able to buy it and keep the M330. It's on order now.
