The Push-On fittings really work nicely, but from a visual standpoint the look might be a little too different for many people's taste. I don't know if there would be a issue from any rules standpoint, but the Push-On tubing is some tough stuff. Once tubing is pushed on a fitting, and it takes quite a push to get it seated, I certainly can't pull it back apart. Price-wise it's probably a bit less than braided, but not a huge difference.
