As for Mech. heads. Rage Grimm Reaper, and other name brands. If the hit is well placed there will be no issue of recovery. But i must say that the rage 2 blade can make up for a not so good hit. Do to the amount of damage it does and the amont of hemoraging. this by no means should let someone think they can take the risk of making a bad shot. Just my 2 cents.
