The CE 350's really are essentially equivalent to the PSE300's. The carbon express designation of 350 spine in reality is 0.337" for the Maxima hunters. The PSE x-weave is somewhat stiffer than their spine designation would lead you to believe. The PSE 300 X-Weave's actual spine is 0.340" They are really close.
If the shafts were the same weight then .330 is a good guess to get the draw weight to 70lbs. However, if they weighed more I'd need stiffer.
The bow is only rated for 70# and I've got two dozen PSE arrows I need to use up before I crank it up another 1.5lbs and buy new shafts.
Oh I see - makes all the sense in the world to me now. Yep for that little gain in upping the poundage isn't worth the cost of 2 dozen new arrows. You'll need that many arrows in Africa and you'll be deadly as you are now. So why change anything with your setup right.
