Post subject:  Pepairing a rolling bridge

Bridge/Top REPAIR QUESTION: 5 yr old Lattice style classical guitar. Bracing seems to be a bit short of structure and bridge is rolling forward creating a slight dome behind the bridge and indenting in front of the sound hole. This has messed with intonation and string height. Several attempts to change bridge saddle height and adjust. Is there a internal structural fix to this? My guess is that this will be a tough fix since the top has the the deformation set in now without string tension. I realize that gluing 2 braces from the sound hole brace back behind the bridge will be a mirror scribe nightmare and will probably kill some of the latttice top sound...but it is nearing the stage of nonplayability...so reduction in sound may be irrelevant.
Any suggestions?

I have not used this but I've heard good things... A lot easier then trying to rebrace the guitar.

Just curious. re: The stewmac bridge solution. Looks like a simple fix. I would expect a period of time from the time of placement and the guitar unstringed to allow the guitar to reshape to it's new stress/pressure point. Would it help to increase humidity during this process and slowly return it to my normal humidity of 45% as the guitar reshapes it's bulging belly?
My belly needs reshaping too....but no device can help with that.
