Now that 749R would be my choice
But if that's too much, you have to consider resale I guess...
05 749S new swingarm
04 999 old swingarm
I reckon the older swingarm will be a big loser in the resale stakes personally (hope no-one takes offence) but the 999 has more grunt, tough call.
There have been several reports of sumps grounding out, but that could be a number of things I guess, for your weight you'd probably need stiffer springs anyway so that would/should alleviate the issue I guess.
As for riding position, I'm not sure, it would be worth checking each one, the frame on my R is different to any other model with respect to rearset positions etc. I have my seat as far forward as possible to get more weight over the front and I'm 6ft tall.
Welcome to the board anyway, where are you in N. Wales? I often pop up to the Ponderosa on a Sunday for a quick blatt!
Oh look the bars open
I'll have a pint of strongbow please
