Last year I switched from Thunderheads (after shooting them for 18yrs) to Rocky Mountain Ironhead 125's. These are THE strongest head made and they fly awesome. I always had subtle flight problems with Thunderheads that gave me grief nearly every year. That is no longer a concern with the Ironheads. They hit exactly with my field points, even with minor setup changes. And they are tough ... I smacked the rebar in a target last year and only the sharpened tip of the ferrule was broken off. The head is still intact.

Any of the heads mentioned will probably work for you ... pick one.

Good luck ... Crayfish
