Wanted to clarify a couple of things.
The regular Serpent LTD was not offered the way this LTD is set up. It's basically a Serpent LTD II with 170 pound limbs vs. 180 pound limbs. Everything the LTD II has this one has. Only diff is the 170 pound limbs vs. 180 pound limbs. The regular Serpent LTD did not have the stacked adjustable pads. Also this Serpent LTD came with Limb savers and the safety is a gun style on this one vs. the regular LTD.
I use 100 grain Spitfire Maxx heads and it was dead nuts at 20 yards. I never practiced further than that. Also, the 100 grain Strikers were pretty close to the Maxx heads. Had to pay closer attention to the vanes.
