Hello there,
Fresh voice, just one opinion.
I have a bunch of OO (various heritages, suppliers), a room allocated for a railway (and freshly updated (finally) with more sockets ('outlets') and recessed LED daylight spots and... two new twin girls who should be in the 'things that make me smile' post.
Moving to Peco code 75, hoping most of the old Triang-Hornby bumps ok along it. May go for some C&L flexi for the spacing and cut a few plastic links to stretch out the sleepers at each end of the Peco points to merge the spacings (though it may not work too well).
Or, may stick 100% with Peco. Time is the real key for me. Appreciate the hand-built track but pragmatically, not going to happen.
On the '6 foot' aspect, I may keep it tight on the straights and ease out on the curves. Will have some 2' radius so may have to play.
Commercially... can't see a new version happening (poor ROI) but as per an earlier post, why not ask? If it was available I would buy it.
Good luck to all.
Cheers, Steve.
