Sonic heads are very underrated but are the best BHs Ive ever used. Penetration is unbelievable! Ive shot around 10 deer with sonics since 07' and almost everyone, regardless of the angle, was a complete pass thru. they are not a big head but they put alot of blood on the ground. They also fly better than any fixed head Ive ever used. I think limbsaver now makes them but I still dont see them promoted much anywhere. There usually about 40$/6 but Ive seen them on clearance on cabelas site and ebay for as low as a 1$ a head.
