7-string scale length
All UV's have 25.5" scale l3engths, and owning a UV I can quite happily say that the scale length doesn't cause flapping around. I've also had a quick butchers at a 27" Baritone Ibanez in a shop to see what it was like, and I did really quite like it.
To be honest, a 25.5 sale length won't flap around unless you go into the realms of detuning, and even then if you get the correct string gauges it should feel acceptable (heavier gauges for downtuning).
However, if you don't want to use a heavier gauge then a longer scale length will make the strings taughter if you downtune, and still allow thinner gauge strings to feel, well, non flappy. Having said that, if you plan to tune it "normally" (BEADGBE) then you may find that the strings on a 27" become too taught.
The other nice thing about a longer scale length is wider frets, which is noticable, and which I thought was quite nice.
Which strings do you find flappy, and what do you tune to? It took me a while to settle on the string gauge for the low B, so maybe the guitar you've played with such a scale length hasn't had the right gauge for you?
Which guitar are you thinking of shipping in?
