Yeh, i'm just trying to get a handle on how much "not much more lag" actually is.

If they can genuinely hit 20psi by 3k as some of my reading suggests then fantastic. If its more like 3500-4000 then its less so.

I'm also intrigued as to using a T34 wheel in a modified T3 housing, as it could work out a fair amount cheaper doing that than trying to find/buy a T34 and if it makes it even less laggy then all the better.
