I'm liking it. It's a lot more of brute strength movement than sumo and I'm finding it really easy to learn and pick up. It works my entire back a ton more too while sparing my hips. I can push so hard on this one without worrying about hurting myself or my form going to shit as much. It's a lot more fun too.
Just yesterday I hit 415x5 with conventional and a month prior I got 405x5 (6 if you count one really ugly rep) with semi-sumo so just after a couple sessions it's as high or higher depending on how you wanna look at it as the semi-sumo. So much more power off the ground but I have to be really explosive from the start to get the lockout which is a change. Momentum seems to be a lot more important on this lift.
I don't understand this belly bounce thing... Do you have to be a little fat for this to matter or is there a trick to this? I'm sucking in a ton of air into my belly standing over the bar and my hands over my head and pressing hard against the belt when I get into position but never felt anything that I could call a belly bounce.
For whatever it's worth, I have a short torso, long femurs, and long arms.
