hi
this does look like it's going to be a superb track so i would not skimp on the power front.

I would not bother with the scaley psu's instead i would go for a fixed voltage one with a output of 15v and 15 amps as a minimum.

Then i would go for powering the flippers independently and daisy chain them up and run 2 wires from the psu to power them...

Last thing you want on a nice big club track is dips and surges for the sake of a few hours wiring and soldering..

hi
as he is using ssdc opting for a variable voltage psu is a bit of a waste

as ssdc has the power options already installed.

hi compared to coppertape magnabraid will be expensive and also increase machining time.

If it's grip you are worried about try some eurethane tyres on a wood track,they are a lot more realistic than using magnets.
