Thanks everybody !!

Good info here. Some of it is new to me.
I'm glad I asked.

I can't say I'm concerned about what the fletch does to the speed when you get out past 40 yards, but the theories are interesting. I like getting close enough to count a deer's eyelashes, and I want to make a good shot every time, so I doubt I'll ever take a shot past 35 yards. Not that it can't be done, I just want to get them up close and REALLY know I beat them, hands down. I'll take the long shots with a gun, but when I've got my bow in my hand it's all about how close to them I can get.

I'm really loooking forward to trying out my feathers.
Thanks again.
