Jamie, do you currently have the shade 3 lens as a flip-up? That's how mine are and I can't imagine living without that feature. The flip-up is polycarbonate, very light-weight, so it's not much more burden on my nose than just the didymium glasses. I love being able to see things brighter (no welding shade) that quickly, but still have eye protection and prescription correction. As opposed to just peering over the tops of the glasses, as I see guys doing sometimes.
You can get the didymium (or whatever the modern replacement for that is) ground to your prescription, but I just wear 'em over my regular glasses, which are vanishingly light (have you seen Silhouette brand, hingeless and frameless, with titanium wire temples?) The frame with the didymium lenses is not specifically designed to be a fit-over, but they fit over my glasses just fine.
This may seem cumbersome to some, but when I take my brazing glasses off I'm ready to go, I don't have to go find my regular prescription glasses that I set down somewhere.
Sorry I totally didn't answer your question, and the flip-ups are not a new technology so you must have tried them already... I'm just afraid you might spring for expensive new glasses only to find you don't like them as much as your old cumbersome setup.
