I have a 28 in draw. With cat whiskers and a loop my patriot dually shoots a 355 grain arrow 303-305. I love dual cam bows. I think that bowtech really shines with duallys and now with the new cams. My speed was exactly the speed posted on my birth certificate. ...which was 315 with only a brass loop. Whiskers slowed things down. I have a very forgiving brace height at almost 8 inches as well. I shot a 400 grain arrow out of a 28 in lx through the chronie to compare to my patriot dually. My bow was set at 66. The lx was at 73. I shot 12 fps faster. That is with a 7 lb difference in draw weight and nothing on the lx string. Honestly, Matthews makes a great bow and has a loyal following. In my area they are pushed more than others due to the pro shop guys at the two local shops getting free bows from Matthews for selling a certain amount. I am not the one assuming this, they tell me so. I also think that their mass weight is too heavy. BUT, they have a good line of bows and kill tons of animals each year and doing well at 3d shoots. Someone mentioned a harsh draw cycle on the switchback. There is no way it is harsher than my dually. She is a rough one in the cold. The dually is set at 65% let off and will get away from you if you let it up a bit. This, for some, would be bad. But, it is smokin fast, forgiving, and now very quiet. I also shoot heavy arrows at 270- I like the speed for KE, not for trajectory. One of my points is this- with the duallys or new cam- you can have super speed with forgiveness.
