I'm approaching about as extreme as you can get with both........I am competitive on a National level in 3D with a compound, and might try it with a recurve next.
As it stands now I'm becoming quite proficient with traditional gear, and will split all of my archery seasons between both types of bows to be able to enjoy both.
It will be the recurve or longbow for PA's hunting seasons, Compound for IL bow season, and then compete with the compound in 3D with the traditional gear for fun shoots.

I might be spending 2hrs one day working on 3rd axis leveling and pin gaps with the compound and 2hrs the next day trying to figure out why I'm shooting a little right at 20 with my Black Widow recurve.

I can tell you this, done right and not overdoing it the traditional shooting has helped my compound shooting by strengthening the stabilizing muscles in my shoulders, back and arms.
