I just bought a Trad a couple of weeks ago. The non-weight-relieved thing shouldn't be underestimated. The tone is definitely affected by that (in a good way in my opinion). But it really does feel heavier than any other LP out there. A LOT heavier. I play seated so I don't have mine hanging on my shoulder. Even still, seated, it wants to slide off my lap to the right. I'm good with it, but it really is different.
Bottom line, not only play them, but take your time playing them. If you're going to play standing, strap them on and see.
Oh yeah, and you can't really go wrong with this choice
