I don't have ARC Pro so am only passing on what I have heard. The way power is delivered to the track in digital is no longer as though the track was one big lane but is powered as two seperate lanes, the analogue way, even in digital. This means that it is impossible to have sections of single lane (where the 2 lanes merge into a single lane) and the CLC, even modded won't work as the mod picks up power from both lanes (left rail left lane, right rail right lane)......it's a phasing issue One analogue crossover in the circuit would make the layout one big single lane - what happens to your "phasing" then? Please post the source of your statement because at the moment I am not the least bit convinced. http://www.slotforum.com/forums/index.php?showtopic=165866&p=1951906
