I got a used BKII in and I'm attempting to be objective about it. It had the serving on one cable coming loose so I took the cable off and reserved it. Did shoot it a few shots first, just because it's a new toy and I wanted to play with it. Well apparently I used the wrong size serving and also served it the wrong direction as I've been having a time getting it to tune. Finally got it close and I'm impressed. As I said it took awhile, but with all that 80 foot pounds of kinetic energy for 29" & 67 pounds of draw is impressive. Haven't shot it outside to check grouping yet so that'll be next when it warms up. I've gotten used to the draw cycle, and I'm actually impressed with the valley, not long but definite and a great wall. By the way I called Winners Choice and they said they'd replace the cables free so that's impressive also.
