What I like about the quik-spin is that they are the same profile as the Blazers, but they are half the price. Don't know about their spin, but they seem to fly okay.
I took one of the MFX and stripped the blazers and replaced with the QS. It hits right with the blazers. All of the MFX will group nearly on top of each other, regardless of the fletch type. The FOBs group right with the MFX.
I an going to fletch Blazers on an ICS and see how it shoots. I tried it with a FOB, and it still hits high left.
Trying to decide on what arrows I want to choose as my primary. I like the flight and cost of the Vapors, but they do not penetrate as well as the MFX, at least in my bag target. I was hoping I could get the MFX dialed in and stick with those........
I have had the ICS since I started shooting, but never really happy with them.
