Generally when Hunting season would roll around, I'd ditch the IC type carbons (Beman, CX, Goldtip, Easton ST, etc) I'd been testing and would switch back to A/C/Cs. After my hiatus the past few years I am unsure- If I can still get Carbon Tech from my local shop, that is what I'd like to go with this coming year-I've not tested any of the newest shafts on the market but from what I'm seeing so far it still looks like the SOS with different names/graphics from the big name all carbon manufacturers- CT shafts on the other hand will hang with A/C/Cs (spine tolerance-wise) easily.
