Thanks for the feedback !!
I wanted to make swapping between oval and road course as simple as possible, and I was hoping Scalextric would make a turnout piece, aka model trains, wheras it's a mechanical manual piece, so you physically can move a lever to cause cars to go straight or turn, thus, you don't need to swap out pieces or force a racer to have to switch lanes, but i digress. So, yes, I only swap 1 piece of track to change between the two, and that is an R1 immediately after the powerbase. The highlighted GREEN straight is removed, the R1 put in.
I see what you mean, about swapping out the lane change on the left straight, and that would work, but, I wanted to try to keep lane swapping as MINIMAL as possible and right now that is 1 piece. Again, if Scalextric had a turnout, like model trains do......ah, there I go again....
I was planning on performing the Arc Pro Mod, https://www.slotforum.com/forums/index.php?showtopic=169186, thus preventing the "SHORT" condition. I never run analog so it's no big deal. I have plenty of Turn Lane Changers I didn't use, but with the mod, I think I can use them, which I may, not sure...still debating.
Looking at when the road course comes back on the super speedway, I'm missing the ability to get cars off of the inside track until almost the point you're going back onto the roadcourse. That's a problem. I think I'm going to need those turn lane changers.
