Not SURE on how you tell if there's too much/too little ski pressure, but if it is hard to turn the handlebars while not moving, it has some/enough/too much ski pressure, if it is really easy to turn the handlebars, it has little ski pressure.

I have Simmons Gen2s on mine. WORLDS better than the offset/stock 03 ZX ski, for me. Much harder to turn on hard snow - two big carbides/wear rods digging in, but it tracks straighter, does not dart, I really like them on firm snow/trails. The Gen2 and Gen1 should act pretty much the same on hard snow.
In soft snow, well, they float. 3" wider than the originals. Kinda have to float more.
Sidehilling on hard/firm snow is the hardest part - the uphill "wing" can hit the crust and reduce pressure on the uphill carbide. That's the only issue I have with them, and so far, it has not been a _real_ problem, just something I've needed to ride around.
In what "deep" snow I've had them in, they're astounding.
