Anyone running a OneUp V3 dropper on a Stumpy Evo S4?

Considering one of these to replace the OE 170mm AXS dropper (operation has been flawless, tbf; just need something longer).

Have fed the numbers (280mm collar to rail; 260mm max insertion) into OneUp's on-line calculator, but it appears to be a marzipan dildo - tried it on 3 different devices to no result.

Any experience of this model on an S4 Stumpy Evo? What length did you go for and how have you found the extension/slamability balance? For reference, I'm a biscuit over 5'10".

Mrsstu has a Oneup V2 at 210mm in an S4 Stumpy Evo.

She's 5'8" and the post is pushed down as far as it goes.

The bend in the seat tube stops it going all the way down to the collar.

Yeah, seems to be the limiting factor. If you remember, and it's not a colossal pain in the arse, I'd be grateful if you could run a tape measure over it sometime and tell me the length of exposed lower post above the seat collar?

Cheers, dude, but I'm in Glasgow! 

I'll just need to ship the bike to you, I suppose...

Jeez mate, you didn't have to get up that early on my account! 

Thanks very much - will go off and ponder how livable that would be.
