If you are comfortable at the 62#'s,I would suggest just building the heaviest arrow I could to get it down to 280.Lots of advantages with that much arrow weight slamming through the other arrows and cutting through the wind on a 3-d course.
Plus,you will carry the yardage better if you misjudge a little.Tom Crowe shoots ALL his 3-d bows on 80#'s and shoots as heavy an arrow as heneeds to get the 280for those very reasons and he is a senior pro.(Atleast when I shot with him 5-6 years ago,that is what he was doing)
You could shoot some thick walled aluminum arrows to get that kind of speed and have a very durable and consistant 3-d arrow.Or high foc carbons but it is up to you to do whatever you want but there are advantages with heavy arrows,even in 3-d.
I would suggest an archery ballistics program to play around with numbers to get the arrow choice narrowed down for you.
Not suggesting going with 60# limbs would have any ill effects,just some more food for thought.[8D]
What to do with "Old" limbs?
) but they're not holding us to that standard.......YET. It's only a matter of time before something comes up I'd like to shoot in.....and I'd like to be able to do it, legally.
