If you do go down the Yari route, don’t think you’ll be disappointed. Sure they’re not a pike – in fact they are a franken-fork (according to Sprung Suspension who extended mine) with a bit of lyric, a bit of pike and the lower spec motion control damper.
Mine are the boost ones and man are they stiff. They’re not quite as controlled as the pike but honestly I’m not sure it’s a 200 quid+ difference. They are a bit heavier but really seem excellent value for money. A bit like revelations used to be!
I bought the 120mm ones and just had them extended to 140mm – that’s a pike air spring so definitely lots of shared components in there.
For comparison I had the 110mm Manitou boost version of the Mattoc on my Stache. Nice fork, very adjustable (too complicated for me), quite stiff and light.
