I've had my UFO ST since last June which I bought in a rush. In that time I've used it for 4x, dirt jumping, drops, downhill racing in the UK and the Alps. It's been down the roughest courses in the Alps through to used on tame xc rides.

It's roughly 44lbs depending on tyres. It feels very heavy to lift as you'd expect and is a bastard on the push ups
However once moving it feels very sprightly. The short back end makes rough tight course much easier than most long wheelbase dh bikes. Even though it's alittle shorter than the likes of an Orange 224 or Intense, it holds its line well enough. It definitely likes to stay planted on the ground unless you tell it otherwise.
If you want to play just give it a big pump on the take off and it can be chucked about with more ease than other bikes of this variety.
It's a bike that is very easy to jump straight onto and ride comfortably but takes a long while to master. The short rear end makes manualing through sections with ease, I can manual it almost as easily as my 4x race bike.
The BB is very low so I had to swap to 165mm cranks which has solved the clearance issues.
All in all this 'bottom' of the range full suspension Nicolai is well worth a punt. The only real failings are the wheelbase does feel to hold it back on very high speed alpine tracks and again, a slacker headangle would help it there. It's a pretty good UK dh bike as our courses are often tight and technical.
As for sizing, I'm 6ft1 and the medium is perfect for chucking around but still long enough for longer rides with the seapost up
