I've butchered the peco points a bit, removing the spring, trimming off the 'handles' on them and soldering jumpers to power them directly (and cutting the default wiring connecting the frog to the blade).
This way, the motors can do their thing and they maintain the tension when thrown to hold the blade in place, and each point is a self-contained powered unit, with insulating joiners to the rest of the layout. This way you're not depending on the point at all to conduct and can weather the bejaysus out of them, including the point blades, and just keep the surface of the rail clean.
I've used woodlands almost everywhere, with a run of Noch / Gaugemaster ballasted underlay too. Both work well but once ballasted the noise deadening isnt' fantastic either way! (still a lot better than cork though!)
