Installation and maintenace experiences of the Hope RX4+

I am currently looking at upgrading my calipers to the RX4+ and was wondering, how the install and liveability is with it. It would go on an older shimano system which is not the best with clearance as is. However I have heard the Hopes are very hard to get not to rub, which I don't like. Also, is the bleed process still so sensitive to small inaccuracies?

Thanks!
