I have the Tony Ryan AND the Longoni. Not fond of either. The first week I had the Tony Ryan, the rubber(?) material inside the tube that keeps the cue stable, wadded up inside of the tube and couldn't be properly straightened out without the same thing re-occuring. I ended up taking all of that material out, gluing in some thin strips of foam rubber, placing a black ankle sock (yes, it was new and clean

) toe-first into the tube, rolling the ankle opening up and over the lip of the tube, getting it stretched into place and taped the sock to the outside of the tube with black electrical tape. Now it works better than it originally did and it is MUCH softer on the cue too.
The only problem I have had with the Longoni is when I loaned it to a teammate and he screwed it on so tight to his cue, it took us several minutes to get it off. I thought we were going to have to saw it off

!
The jury's still out, but I'm not so sure that I'd use the Longoni on an expensive/collectible type cue where the finish was an issue.
Hope your Tony Ryan lasts longer than mine did. If it doesn't, at least you have a reference for repairing it yourself.
