If you're going for a stronger setup and plan to shoot a 5mm Axis 340 @27" shaft - I'd personally run 100g points, 50g Iron Will HIT inserts, and use the Iron Will 10g collars on them....if you are planning to hunt elk. Your finished arrow weight will be right in the range you said, maybe up to...
I've killed mule deer and elk with SEVR 1.5's. You'll be getting passthroughs easy with your DL/DW and finished arrow weight. Just put it in the right spot ; )
