RE: fletching type...
I just put my Jo-Jan away after refletching a 1/2 dozen of my Axis STs. I put 2" Blazers on with a right helical. The vanes I took off were 2" Blazers with no offset or helical. My arrows flew great with the old vanes that were on the shafts the day I bought them but I really wanted to try with an offset. That is the only reason I changed them. I have shot them hundreds of times and they were like new. Blazers are tough and I like how they fly with both my feild tips and my Muzzy's. One arrow has passed through 2 hogs and those blazers were still in great shape after I washed the blood off.
