I'm looking at the JD, due to the proximity of the trigger to the bowstring at full draw.

I've got my mongoose set about perfect right now, really loving the trigger, even though there's not much travel, the way I'm engaging it is doing wonders for my consistency.

If I can get good trigger action from the JD, it looks like I can gain a solid 1"+ of draw length, giving me more energy at the lower poundage. I recently installed a 27" module, actual is about 27.75", and it's about perfect. However, I gave up 10 fps when doing so, and 4'#s of ke. Not alot, but I was already at the lower end of my comfort scale for the 1.5" cut rocket's I plan to shoot.
