I stopped using the Bosch points because they weren’t ventilated, and when the got that tit on them I couldn’t re-gap them properly.
The ventilated points wear smooth, and those lubripoints have such a nice wick on them for lubrication and they are such a pretty copper plating  😊

But with the Mark 10, you wont get the tit and then they are probably the best option out there.

I've always just used the standard Bosch points, but I'm careful to clean and lighly grease the cam periodically. I stock those points, as well as Bosch cam grease. Lubrication of the cam almost completely eliminates rubbing block wear, but it also keeps the cam itself from wearing.  

It took me decades to realize that abrasive grit on the rubbing block will wear a  rough groove in the cam, which then wears the rubbing block quickly. I suspect this is the fate of many cars that start to require frequent dwell/timing tuneups. Almost 100% of the distributors I rebuild require touchup of the cam surfaces to restore their shape and finish.

Yes, I didn't mention that, but you have to be careful not to touch those terminals, AND you have to remember not to connect your timing light or dwell meter to the actual + or - coil terminals. The "outboard" CDI terminals are now the ones to use for 12 V and points dwell.

It's easy, once you realize what's going on.
