Any of them will be fine, the manufacturer is less important than getting the correct spring rate. K Tech also do springs for the SV650.

The Racetech Calculator suggests 0.85

I'm 12st and have the k-tech linear 0.85 springs, just about right for me, I'd reckon they'd be fine for you too. Way better match than the OE springs anyway.

I use Silkolene PRO RSF fork oil, one of the better spec oils IMO (very high viscosity index VI, which means it doesn't change as much with temperature). Personally I find the PRO RSF 7.5W suits me in the SV, but be aware that the nominal viscosity of that is more like a typical 10W oil (around 35cSt@40C). Check out the viscosity table in the bible here .

I've had race tech and ohlins springs in my old curvy, couldn't really say there was a difference except that the ohlins springs cost about a tenner more.
