Thank you and keep us abreast of your progress.
Tubular won't need as much effort. Flex will try to become straight again and needs a very secure hold down, it needs more resistance to lateral motion..Ideally if elevated it would sit on posts solidly connected to the bench, and braced enough to stay plumb. but that takes a different skillset and more effort.
Tubular can effectively be press pinned in place pretty loosely and stay put. E.g.. at one time I set long screws solid into wood. Now I just push shorter screw into those holes with my thumb and it stays put (green foam). It acts as a dowl to stop lateral motion. If you aren't going to carry it around, no real need to attach down, just stop lateral movent around curves and (less) in long straights just enough to keep them straight.
