I haven't sat in one for awhile, but I believe the Pro-90's to be a bit smallish for a larger person.
If you're just tall and skinny, they're actually very comfortable in the seat, but not tall enough in the back for full support for every body.
If you're larger in girth though, I'd say go with the Elite for sure. The size is actually what makes them all, but especially the Pro-90, so great for an EB. Low and compact. But that same nice feature is what makes them questionable for larger drivers.
But that's just my "opinion" and since seats are a very personal thing, it'd be great to find some that you could sit in first.
For those within hitting distance, it's a perfect excuse for a road-trip to Wild Horses. Probably not an option for you volnut, but thought I'd say.
