Well, with that arrow, your on the edge with spine. If you get a 30" arrow, your might be too weak. But with a 29" arrow, you would be ok. I imagine with a 29.5" draw, you want arrows at least 30". You might have to back down on poundage about 4lbs. Only bareshaft or broad head tuning can tell you for sure. I shoot 340's at 29" arrow length, and had to lower my poundage down to 66lbs for broadhead tuning.
