I use EXP's on my electrics. Sadly, they will not go along on the boat. I'll try a set on the acoustics and see how they do.
Not all adjustments are via the truss rod; just as not all twinges in the guitar are not in the neck. Humidity and swelling; or lack of, can cause the top to expand/shrink and arch or pop the bridge. BTDT!
I even went so far as to look into the composites. Seems that I can get a decent spruce top bear a dozen times over for the price. Only one close to realistic was the Asian Martin all-formica (high pressure laminate...yeah!) wit the lam neck for near $700...still too high$$ fr my tastes for a boat picker
