Re: ring height

You can adjust the ring key heights (relative to the chimney tops) without altering the venting.

If you are wanting to lower the ring key heights, don't use a pad iron and apply pressure to the pad as that can compress it and cause a leak. I use a flattened metal rod placed between the pad cup arm and the joint surface to do that, or between the ring key arm and the joint surface to make the rings sit evenly in relation to the chimneys (instead of being high or low at one side). The flattend metal rod can be covered with thin card to prevent it marking the wood or the underside of the key arm. You can use a ad iron placed between the front of the ring key and the chimney to raise the fronts if they're too low.

I aim to make things as concentric as is possible (but not always with some instruments) and so the ring keys are at an even height all the way around the circumference of the chimney no matter how low or high they're set (according to the players hand and finger size).

I generally set thumb rings pretty much flush with the thumb tube as thumbs are usually wide, plus it makes it more comfortable when using the speaker key. This also depends on the cross section of the thumb ring - some are evenly radiused on top (eg. Selmer and Yamaha), some are radiused on the outer edge (eg. B&H and Buffet) and have a sharp inner edge and some are concave (eg. Buffet DG Prestige), so the cross sectional shape also dictates to how high or low they chould be set according to the player's hands/fingers.
