the 999 all the way,I've got a 999s 04 and I'm 16 1/2 stone and 6'4, the pegs were in the low position but my boots were wearing out so I'ved moved them up as far as they can go, it's not high enough so I've put self tappers in them and it's working.
you will need to firm up the suspention but the bike is good for people our size, thats why I bought a 999 in the first place, it's gone full circle with the jap bikes now being smaller than ducatis.
ps you can get a 999s new but 04 model for 10 grand and being a S it will be worth more when you sell it.
