I switched to 15” front / 10” rear this year and won’t look back.
For the Atlas, which is so big, you’d want the mechanical advantage of long stabs to see real effects.
Overall, you end up with a heavier bow, but it’s not that hard to manage in the woods (and I hunt the Oregon coast, which I’ll hazard is the nastiest and thickest terrain in America).
If most of your shots are 35 yards and in, shoot whatever you like. But as shots get longer, the longer stab setup will quiet your pin float, reduce torque on shot, and should result in improved downrange accuracy at distance and reduce those WTF fliers.
A balanced, tested stab setup is like a heavy rifle on shooting bags. Just shoots better.
Levi Morgan has a good video:
Jesse Broadwater’s Vimeo series (you have to pay for it) has the best how to guide on dialing in a stabilizer setup. His tips are for target bows, but the steps are the same.
