Your other option might be to talk to someone like LoCo about fitting a Dual Flow rebound damper from another fork, maybe a Revelation. It’s very similar to the Push upgrade and makes the forks much nicer over repeated high speed stuff, like hammering through rocky things in the Peak.
You could also fit an RCT3 compression damper which would help on the compression side. Obviously the fork would still be a little bit heavy, but if it’s in good nick otherwise it might make sense.
I’m still running some old Pushed Pike Air U-Turns on one of my bikes and they do work really well. Not as super plush and supple all round as the new Pikes, but great on faster stuff where they used to occasionally get overwhelmed.
So you might have missed the bus on the Push upgrades, but you can still improve your current fork if you want to. Or maybe get a basic modern RS fork like a Sektor with a 1 1/8 steerer then do the same thing to that.
