I think they're a decent head. I tried my darnest to switch to Muzzy. Heck, Muzzy even sent me some free Thunderheads(OPS...I mean Muzzy's)with my name printed on them once when I won a hunting trip they were co-sponsoring. I just couldn't get them to fly as well as my Thunderheads. I tried 3 different weights in an effort to make the switch. I always ended up going back to Thunderheads by the time hunting season rolled around. However, I found a new deadly flyer this year just like RIckmur. I'm carrying a quiver filled mostly with Shuttle T's and one Thunderhead. The Shuttle T's are deadly accurate. And aren't they "GAY" looking.[8D] Atlas, I think he's 19.
