There' s been many ah threads on this head. Some don' t like it' s small size (100 Gr.- odd that it' s 75 Gr. is larger than it' s 100), some problems with blades falling out. Supposedly it does fly like a field point. And the blades are SCARY sharp.
Do a search for " ultimate steel" . Hopefully I' ll be tring ' em out this year.
PS: One thing is for sure, they' re cheap enough to just go out & try ' em without wasting much $.
