Hey,
Can't make this one - at Silverstone on the 17th May
Did the GP last year and loved it! Such a long circuit and a lot of corners to learn. It never feels crowded, though don't be too surprised when you get absolutely nailed down Hangar straight. Little SV is no match for the sportsbikes here (corners are a different matter though).
Can't remember exactly what tyre pressures I ran on the SV, maybe 28f/30r on Z6's? Depends what rubber you're on, but there should be a tyre guy there to advise.
Have fun
Luke
