I had one of those things years ago. Was good but now I just slide my arse off & hope the nads don't get a hammering
Dodzy designed the one I had & got it built in a factory in China that make office chair droppers. I had the Gen1 version that kept going down when you didn't want it too.
I took it back & I asked the local dealer when the GenII version came out. He opened a mag & showed me one - except it was made by the Chinese company who used Dodzy's design & marketed it themselves-leaving him out of the equation- cheeky buggers.
If I was you Phil I would borrow a fully sus & ride on that. the difference is well worth the money spent. You will enjoy it more & want to ride more. Hardtails are old technology whilst still have their place don't offer as much niceness as a fully.
There are some good bargains to be had on Tme but your better bet is asking around your workmates if someone has one they they are selling cos the majority of MTBers are upgraders by nature
As far as the 29/27/26 wheel size once again I'd try a few & determine what kind of riding you'd do.
In life as in dance Grace glides on blistered feet
