Don't make the change. I made the change last year. Since then, I've shot 6 animals and blew the blades of 5 broadheads in the process. Blades came off @ inpact leaving a small exit hole the size of a fieldtip. I contacted Rage for my money back like advertised on their commercial after loosing a pig this week. They offered to replace them if I'd send them in, but never did give me information on how to get my money back. I'm back to using my spitfire's; should have never made the change in the first place. If it aint broke, don't fix it!! Have a great season.
