Rob,
I agree with Larry (although its all a very personal thing) that the Reeves 'pieces might be a consideration when you get your horn. 43 or 43W rim.
Seeing as Larry has mentione Chuck Findley ...
www.chuckfindley.net ... Readers ... if you don't already have his CD "Star Eyes", get it! There are also some photo's on the great LA studio days!
Hey Larry when you mentioned getting that "Las Vegas Lead Sound" ... You "know" what horn most of those guys are playing ...

( Sorry had to toss that in there. )
Michael
