I'm using HO Code 83 Flex track... checked a couple of the online suppliers, but didn't see any code 83 rail joiners. Up to now, for my preliminary track layout, I've been using code 100 rail joiners. So, when I lay the track down permanently, do I just use the code 100 rail joiners? Or do they make something a little smaller and less conspicuous? What do you guys do?
