Can you post some photos of the Knee Machine?Thank you so much Jammers. I really appreciate all your input. I think I will get the extra boxes since I do like to mess around with different fin settings @messierishome. I do love the smooth glide feeling of a single @DanSan, @R1H, and @Ricksurfin. I've been told Bruce's boards are really fun with the fin pushed all the way up @jtsfla.
I have a Knee Machine from Bruce that is 5'8' x 22 3/4 x 2 1/2 with the fin placed in the middle. Its so skatey and fast as a single with two small side bites. I wonder if the differences will be significant between a 7'9" and 8'0" V8 for a guy my size @messierishome and @DanSan.
Again, thank you for your support.
