Bob,
 
Since I was using Tracy's redrive, the only options I had was fixed or electric (ground adjustable or C/S).  I had heard about a group buy that was being put together for the M/T prop, so I jumped on the bandwagon and went with the M/T electric.  M/T will paint the prop whatever color you choose.  Jim Ayers was the M/T dealer that I went through.  
 
Keep in mind that the threaded inserts that Tracy uses are a different size than what M/T uses and he won't do a special run for the M/T guys; says it is too costly to make changes to the production run.  I understood his point, but that still didn't help solve my problem.  So, if you go the M/T route, plan on purchasing a set of M/T bushings and having your prop flange re-machined to accept the new bushings.  These are press-fit bushings, so the hole diameter is very tight tolerance for a non-standard size hole, requiring a custom ground reamer ($100).  Tracy says we don't need the larger bolts, but M/T emphatically disagrees.  I went the safe route and installed the M/T bushings.   
 
If you had gone with the Marcotte redrive, you could use a hydraulic c/s prop, but the c/l of the prop shaft is different than with Tracy's, so if you haven't planned for that, now would be a bad time to change over.
