Welcome to VAF!
Bruce, welcome to VAF.
There are hundreds of RV 10s flying now, and that gives a lot of credibility to the factory parts, at least as I see it.
Depending on what the airport constraints you fly out of are, it is probable that the factory stuff will do just fine for you.
That said, I have to admit that I installed the Matco front axle in my 10, and am glad I did so.
If I were to do any more mods to the wheels, I would probably first take a real hard look at the sealed bearing setup that Alan at AntiSplatAero is doing.
As far as I know only one person has reported using the new Matco brake setup, and he seems happy with it.
One big drawback to the factory brakes is that the pads are not very common, and cost a lot more than a lot of similar ones.
Also, consider adding long bolts and booster springs to the brake pedals/master cylinders.
Good luck, hope this helps you a bit.
