I just got mine on tues. Love the way it shoots but man is it slow. I have a switchback 27"draw 58 lb 314gr arrow @ 275fps. The LD 60lbs 27'' draw with same arrow 266fps. Both with 80% cams. Both with same things on string. I was expecting maybe 2 to 3 fps less. Everything is in spec. Any ideas to get more speed?
