If you didn't see my answer on that thread, then I am fairly sure that you won't see this one either. :p
Did you sell your SK too?
You started out by saying that you like the Supermag grip, and then dumped it for a Super K. Then you said that you shot the Super K better. I have never shot a Super K, is the grip a little lower than the Supermag?
That you shot it better is no surprise, regardless of grip. The higher mass weight and longer limbs would be a vast improvement over a 48" bow for holding on target and forgiving release flaws.
It just sounded to me that you liked the Bear grips, and a short, sweet-shooting, Bear-gripped bow, for me, is a K-Mag.
