For me:
BW PL love the grip, rock solid, good shooting, good speed, very smooth on the draw, little thump in the hand, nice solid feel with nice weight in a LB, could kill somthing by beating it to death with the bow. Limited options for riser look.
Peregrine grip is ok, light whippy limbs, fast, quiet, very light in the hand, a lot of options of looks and great shooting.
I LOVE the first Peregrine I ever shot. I was real impressed. The second one was a dud for me. It was loud and I didnt' like the feel of shooting it at all. BW's all shoot the same; very consistant.
