I am a Dwyer Junkie! My favorite bow is my 66 inch Dwyer longbow. With fast flight, it shot great, but did have hand shock ... noticable! I went to a 15 strand 8125 string with musk-ox silencers. No hand shock and it is quicker by a few fps and is DEAD slient. Also, my bow loves 7 1/8th, inch brace heigth. I am going to try 12 strand 8125 string just for kicks, might pick it up another fps or two and still make it quiet and shock free. I shoot about 10 grains pre pound of draw weight, but it shoots 11 to 11.5 real good also.
Good luck.
Bob.
