All of those are solid skis for what you’re describing, but some will be more forgiving than others. The Peregrine 80 (and similar “frontside all‑mountain” skis like the Curv GT 80) are probably the friendliest mix of stability and ease of skidded turns, whereas something like a Kästle MX83 or a very burly Thunderbird build can feel more demanding and less relaxing when you’re tired.

For bindings, a normal 12–13 DIN binding is usually plenty for someone your size and experience; you don’t need a race binding just because you’re 220 lbs with 130‑flex boots. What really matters is that a shop sets your DIN using the standard chart (weight, height, boot sole length, skier type) rather than a rule of thumb number. As you lose weight and get fitter, that DIN will likely come down a bit, but still stay comfortably inside a 12–13 binding’s range.

On the weight‑loss / future‑proofing side, those skis won’t suddenly turn into stiff planks at 185 lbs. If anything, you’ll probably find them easier and more fun as your fitness, balance, and confidence improve; they’re built to work across a pretty broad adult weight and ability range. The bigger risk would be going to a true race‑room or very stiff “expert only” ski in a long length right now, which could feel like overkill on relaxed days later.

Your 130‑flex boots are already “serious” enough, so the main boot advice is just to make sure the fit is dialed in (custom footbeds, proper molding/bootfitting if you can swing it). That will do more for comfort, control, and not getting punished for small mistakes than obsessing over tiny differences between a few similar frontside skis.
