I think Ill skip that idea.The STOS IS a good head,flies good and sharpens very easily. Started trying them 3 years ago .Shot 7 deer,all but one where perfect hits,the other a tad high.I Recovered all the deer.That being said I wasn't at all impressed with the blood trails on average.Sharpness or penetration where not a factor.I Guess IM just use to three blade blood tails,been using them since 1991.I like the fight charactertics of a two blade,IM going to give a single bevel a try .
