I bit the bullet on these and bought a set from OCUK just in case they became unavailable later, and SO glad I did, I knew they'd feel better as I've had PBT on a previous keyboard (some caps mismatched) but my word these feel fantastic, I have 1.5mm o rings on them and the weight and general feel is just great, and they're making less noise than the original set.
The only down sides at all are no PBT FPS key kap set for WASD, I'd become fond of those raised outer edge keys, but I'll adjust back to comparatively flat keys again, and some keys are noticeably a bit dimmer but everything is still very easy to read.
Thank you SO much for doing this Corsair, I hope for everyone else's benefit that you consider having these as default options on some of your mechanical keyboards.
Advice for anyone with a Strafe RGB, for some reason my spacebar pins were glued, so be very careful removing your space bar, I had to raise it up carefully and then use a craft knife to gently press in between the post and the base of the key and lever it up slightly moving around the seam, the glue cracked leaving no damage to the pins or posts.
