I have both a Tracker II 20ga and a 20ga USH. With Lightfield hybred express the Tracker II is an absolute tack driver and with 2 3/4" buckhammers the 20ga USH is a close second. If I'm still hunting I like the Tracker II because it is lighter,if I'm in a stand and my kid doesn't already have it I will use the 20ga USH. I had the Tracker II drilled & tapped and wears a Simmons pro diamond 4X32, the USH wears a Bushnell Banner 1.5X4.5X32.
