In all honesty I will not recommend any bow if you are going to shoot those 5.5 grains per inch speed pro arrows out of it. In my opinion shooting too light of an arrow is just asking for any bow to blow up.

If you want speed with a relatively forgiving design then you are looking at a bow with a hard drawing cam. You can get a longer axle to axle length, longer brace height bow to shoot very accurately but if you want speed out of a bow with those attributes then you need to resort to either a heavier draw weight, lighter arrow weight or a harder and more efficient cam style. The previously mentioned Patriot single or dual cam would be a good place to start as both offer brace heights of at least 7 inches, IBO speeds of at least 320 or so fps and long riser designs to help promote better weight distribution.
