My rule of thumb when it’s not absolutely clear is, the first thing goes with the first thing. So… you said
9V track for PF
3:1 ratio
but I was pretty sure you were looking to get a larger layout in exchange for giving someone who’s traditionalist some of what’s hard to come by these days… so I figured I’d mess with you help you (and the masses) out by clarifying.
Bummer we won’t see you, but congrats or whatever. 😉
