These newer 3 blade don’t have issues with tip roll over like some earlier ones did.
Shooting mid 50’s, I agree that it’s a coin flip. I shoot now lower poundage so I go with 2 blade…why use a 3rd blade resistance to slow an arrow further when 2 will do the job properly placed!
If you can get and keep the 3 sharp as the 2, go for it. Sharp is the key…placement and sharpness!
