U think its overkill because of the g27? Or overkill if I keep it single screen? Do I need a better wheel or just a bigger one (momo wheel swap). What about triple screen revolution with g27? Does the ozone compliment the g27 better?
Yeah a bit. The G27 is a great wheel and the oZone is basically built for it. I wouldn't upgrade if you're happy with it... I only went from G27 to a T500 because I lucked into a great deal (basically a T500 for half price "brand new") and was like, ehh, why not?
With the oZone you spend half as much for basically the same performance... same seat, plus it includes sliders, keyboard tray and shifter mount, ect.
As for triple screens, they're awesome, but not really realistic on PS3. If you ever go to PC games tho, worth doing for sure. That's the biggest oZone vs. r3v difference IMO, the oZone has the single monitor stand attached to the rig, while the r3v comes with a separate stand. If you do triples, the separate stand is nice and gives you a pretty fair amount of monitor options (I think up to 32 inches once you buy the triples kit). The oZones single mount is nice for one largish screen, but for triples (with again, an extra kit sold separate) it's a little far away since you need to use smaller screens (24 inches.)
Anyways, hope that helps. I personally have a oZone (g1 style, the new ones are more adjustable) with a T500RS, TH8 shifter and a homebuilt triples stand with 32's and I love it, although my plan is to someday get a r3volution and the triples stand for it, just because it looks cool and fits the T500 a bit better. At that point I'll probably just reporpose the oZone as a single screen console rig if I don't find it a cool new home.
No matter which one you go with, you'll be happy. They're both very robust and great value for money. Good luck!
