If you really like to build, you might consider Jim Hiller's Option 120. Really flies well on a 120AX. He cleaned my clock (and everyone else in Dist *) in Advanced pattern with it. There are at least 3 guys I know that have recently built or are building them now.
The last contact info I had on him is
[email protected]
I'll try to get him tonight and get better contact info like a phone number.
