I've had both light barrels and heavy barrels. The heavies tend to be track drivers, but they are unnecessarily heavy.
Good barrels aren't hard to come by these days even in light profiles and you can get a better handling predator rifle without a weight and length penalty.
The WO upper you linked has a couple of things that would be problematic for me on a predator rifle. To me, it is heavier than necessary, threading is 5/8-24 (usually used on larger caliber suppressors) has a .875 gas block and depending on length, a slow twist if your going to shoot heavy for caliber bullets which a lot of coyote shooters do.
Personally I would trade barrel length and weight for a suppressor even while shooting supersonic loads. That may or may not work for you though.
