LJ hop on highway

I am just completing a rear conversion on my LJ. Did all the work myself. I had a straight long arm in place for a long time on rear of jeep, bolted to the oem brackets on the 44. I just swapped to a truss/bridge and triangulated the rear uppers, relocated coils straight up/down, yanked the tracbar, basic rear build. I've been running outboard shock setup for a while, so know that isn't the cause of my concern below....or so I think. With this setup, Jeep drove excellent before even up to 75 or so.

On the first drive yesterday out of the garage, the Jeep drives great until you get to 65 and all of a sudden it gets this nasty wheel hop in rear, possibly a vibration, but more of a hop I feel. Does not feel like a driveshaft type of feeling or anything. pinion is set to what I think is dead on and the upper arms are at a good level & angle to the truss. Don't know much about triangulated from a usage standpoint, read plenty on install and setup. I don't know know if this may be casued by angles of the uppers or something related to that possibly? Are there some "do's and don't's" I may need to know?

Anybody with similar build run into something or read something somewhere else like this?

Just trying to figure what may be the cause(s) here. I surely didn't think pluckin the tracbar would do this.
