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.
I'd say you were talking about a 400 spine. Mine is the exact oppisite. The 340's I shoot are too stiff at about the same set up. Last I looked that spec was on the cusp of the 400-340, not the extreme end of the 340.
I'd go with the elites in that shaft. I like them better.
