I have been using Bravo 1s for a good while now. The stock Bravo 1 will need work for a Cat to run efficiently (dual holes, cut barrel, B and B). I have been running a 28P Bravo 1 XS from the day they were made available to the public. Great prop out of the box, I sent it to Mark Croxton for some tweaking (4ea pluggable PVS holes and BandBed). I run it on a 2009 Puma FTD, great hole shot, super great lift and no issues with speed (low 80s all day). The only issue you might have is plugging the 1″ holes if you need too. I have tried trophys on Cats more than once and they seem to burn out quicker on hole shot and they love to throw blades, I need to say that again, trophys love to throw blades. Hope this helps.Gerald
