I meant to go into a little more detail about that, got sidetracked. Part of it was cost/ease of obtaining. Part of it was COVID delays, but it took months to get the extrusion. Part of it is that it's an extra step; I had to build the extrusion frame and then build the panels and tongue them to fit the extrusion. As opposed to just putting together a simple cabinet and top. And if I damage it, it may involve significant disassembly to replace. I kind of wanted to use it for stiffness and straightness, but in retrospect adding T track to wooden carcasses probably would have been a better option. Especially as 20 profile isn't the same size as typical T-track and associated tooling. It is stiff and strong and straight though.
