If you get a bronze gear - you might always be wondering about it’s condition, and then you’ll have to pull the distributor regularly, and you’ll be checking your oil for bronze particles…
It seems that even if the bronze gear doesn’t wear that fast, it gives one some concern…
I did some investigation of the Kevlar (composite) gears, and I saw enough bad reports to know that I want to stay away from those as well.
I guess I am lucky that my camshaft seem to be compatible with a standard cast iron gear, and have had the engine apart often enough feel confident in the gear.
I have done the modification to the oil gallery plug that sprays oil directly onto the gear/cam interface. Rene - since your motor is apart - I’d recommend that simple modification!
I have never run the melonized gear, but that would be the approach I would consider first.

Rocky, I already drilled the 0.5mm hole in the plug to improve the lubrication of this gear 
I think I'll go for a melonized coated gear.
