I hunted all of last season with an EWO one stick and UP.It was great but I'm not a fan of slanted platform.I really don't think they're any more comfortable and they limit you on how you can take a weak side shot or just stand.I got the flat UP last week and had a chance to play with it briefly.In my opinion it's a huge improvenet over an already great set up.I was easily able to shoot from my weak side and easily stand and turn any way I wanted.I doubt I'll even use a ring of steps with this.
