I voted for the RoadBlasters type without looking at the pic (didn't realise they were there at first)...
I own a RoadBlasters wheel and like the grips a lot (thus my vote) - but they are totally different to the ones pictured! My ones do have a real trigger - I haven't ever looked at a Star Wars yoke close-up, but I'd say my grips are exactly the same as SW ones.
So after seeing the pics, I would agree the Happ ones look better. That said, they look plastic, are the RB ones metal?
