Firm Feel or other similar steering box owners...

I see guys asking questions on here quite often, and see that most with the FF boxes really like them...

Well, my power box leaking, and I was thinking about a Firm Feel box, but I've got a 13" wheel, and I'm not really sure what I want to do.

I may just end up with a rebuilt one, or see how hard these are to rebuild myself...

BUT, my main question for FF owners, what diameter of wheel are you running?

I'm running an original 15" rimblow with a FF stage II box. Steering isn't at all heavy. I'll be changing to a 14" wheel soon. With a 13" wheel, stick to stage I or II and I think you'll be happy.
