I am a 31" dl and compete with Vantage Elites. With spiral cams I have no problem getting over 310 fps shooting less than 60 lbs with an arrow considerably heavier than IBO minimum.
With the low let-off of the Spiral cam at low poundage you get a super-hard wall, enough holding weight for a crisp release and a smooth draw cycle.
With the 2000 limbs you get "just enough" feed-back to know if you have tension/torque issues.
I'm not sure what more you could ask for
