I'll second that. I met Rick last year at the Eastern Sportsman Show in Harrisburg PA. He let me shoot a 58" 50# @ 28" Stinger demo bow. He just hnded me random arrows from his back quiver...Woods, aluminum, carbon..Have no idea the spines. The bow shot them all. Granted the range was about 8-10yds.
My bow shoots Heritage 150's, 250's, 2018's and POC's at 20yrds with 125 gr tips fine...I have a Savannah that is the same draw weight that won't come close to that. It's picky with spine.
