It is not what you can draw and shoot while warmed up.  If you are hunting, it is what you can draw and shoot easily while sitting for three hours in rather cold temps with no warm up.  There is a difference  

I played with 4 fletch when I was first getting started because I was afraid if I wasn't paying attention, I would accidentally shoot an arrow with the cock feather in. I do think they straightened my arrows out faster but now (20 years later) I realize my arrows weren't tuned very good or they wouldn't need to depend on the fletching to correct them. I didn't notice them dragging the arrow on close shots-20 yards or under but past 30 I noticed a good drop. You should probably stay inside 20 for a while anyway. Also. you can shoot feathers cock in and not hurt a thing because they lay down against the riser. A vane won't and will cause fish tailing.

Just a heads up when I went back to Trad.     bows, I shot a 70lb compound @ 29inch draw length. With trad bow 55-45 & 27 draw length !  you'll have a real learning curve to over come. But Alot more fun  

Yes, that is what I mean !
