Buying a 150 sight-unseen. Do you guys see any concerns with the underside of it?

That is a good thing. JLG can be performed on any 10-13 460 now on demand before failure. I took mine in when JLG came out in August 2019 and had my system modified with updated component even though stock wasn't broken.
