My bow only has about 65lbs of pull. Is this enough to shoot mechanical broadheads? I am thinking of trying some Rage Broadheads. I have also looked at Spitfires. At my poundage, what would be reccomended? I currently shoot Thunderhead 100s.

plenty , I shot 60 lbs last year with vortex heads and had complete passthrus , the broadhead you have chosen is great for the poundage you are shooting , no worries .

Never had any beef outta my Grim Reapers, even with my old bow at 55 lbs and maybe 235 fps on a good day I had 3 out of 4 complete pass throughs with no deer going further than 75 yards, to me you can pick whatever kind of mechanical broadhead you want and most shoot the same as your field points, I shoot Grim Reapers because I get em for cheaper than the others, the pros of knowing the pro shop guy!!
