Do either fly any different?. Why would you or why would you not use a 3 or 2 blade?? Any benefits to either?
I've never shot the 3 blade, but i wouldn't imagine much of a difference, with the design being the same. only dif i tihink is that the 2 blade is going to be a wider but narrow hole (i could slide my fingers through a shot last year) and i think the 3 blade is going to be a little more 'roundish' cut 2 blade entry cut
