For the record, I'm 6'2" 265 (bit of a belly), and usually wear XL in pants (most recent being Warrior QRL pants, Bauer supreme 190 girdle before that).
I got both a Super Tacks and 7092 girdle in over the weekend. The 7092 was used once, the Super Tacks was "pro stock" and brand new. I'll be skating in the 7092 tonight and I'll update with my first impressions. I really don't see any difference in the padding aside from a few small things. Some of this has been mentioned before.
back of the thigh padding - Segmented on the Super Tacks and maybe slightly thicker, non-segmented on the 7092
cushioned area to the right/left of the tailbone protector - lots of vent holes (honeycomb like) on the Super Tacks, Solid on the 7092
Belly strap - Extra cushion above the strap on the Super Tacks, no extra cushion on the 7092
Shorts/Liner - Super Tacks has it, 7092 doesn't and is a true wrap style.
The weight in my hands feel essentially the same. Squeezing around on different parts, they seem to have the same amount of padding throughout the girdle. There obviously is a little more adjustibility to the Super Tacks with regard to the spine protector and the height of the thigh pads. While the 7092 isn't quite adjustable, because it's a girdle I can still get it strapped down where I want it to. I may slightly modify the parts that set the height of the thigh guards to raise them up just a hair, but even without doing that, I think these will be plenty comfortable enough. I'm very interested to see if these will stay up as well as they seem like they will. Normally with pants I wear suspenders to make sure they stay up well, and even with my Supreme 190 girdle I added suspender buttons to the shell to keep them up. I hate the internal belt in my Warriors and the belt on the Supreme 190 as they both are more internal and just dig into my hips.
Size wise I'm definitely on the upper end of the sizing for this, but mostly just in my belly (the velcro is just barely all the way on there, any fatter and it'd be a no go.)
I really just don't understand why they added the little shorts liner to the Super Tacks. As they are, I don't see them serving any purpose at all. I'd understand a little better if they had stock tabs and maybe a built in jock/cup pouch, but without those it seems like a redundant piece that prevents it from being a true wrap girdle. I'm going to try and take some side by side pics of the areas I'm talking about as maybe a little better comparison. Either way these seem to both be pretty well put together, very protective, fairly lightweight, and very mobile.
UPDATE: After skating with the 7092 for a couple skates and then the Supertacks, I’ve ended up with the Supertacks. The 7092 worked great, but I have weirdly proportioned legs and prefer fairly short pants/thigh guards so the adjustability on the supertacks won out. The belly pad/fastener was a bit short on both and I really don’t find much value on the actual pad there (I’ve got plenty of “natural” cushioning). I ended up unstitching the belly pad and replacing it with the elastic strap off an old Supreme girdle. Also, I found the stiff and thin (3/4”) belt to be uncomfortable and replaced it with a 1” nylon tube webbing and a heavy duty YKK buckle. VERY happy with this setup. All of the comments about these two running a little small are probably true, especially if you’ve got a belly, but very easy to fix. The only other place I find them fitting on the small side is the thigh strap, but if that was an issue it’d be an easy fix as well. The inner shorts on the girdle are a little annoying, but big and stretchy enough I can easily put them on/off while wearing skates. I do feel like it does a better job keeping the butt padding in place and keeping everything a little bit of a close fit. I may mod it to add some velcro to function completely like a wrap girdle.
