It seems that a 100grain head wouldn't give you enough FOC for those heavy arrows. Try to get at least 11% on the FOC and see how that helps with broadhead flight.
Now, to actually answer your question. Steelheads would be no problem. The Shockwave is a bit big for a setup with KE in the 40's,IMO. I'm still ambivalent about the Rage and it's 2" cut. Right now I'm using the Tekan 2 and hope to produce a late season field report. Be sure the Tekan is legal in your state before purchasing.
