The neck on those is fairly thin and thin necks, in my opinion, are more prone to reacting to string tension. I actually felt that the Fender strings supplied were exerting a little too much tension and swapped them for a lighter gauge (Rotosound standard lights). This, combined with a little truss rod tweak has given me a very nice action. When I tweaked the rod, I gave the neck
gentle pressure in the direction I wanted it to move, to avoid compressing the wood.
You obviously weren't after the Geddy tone if you switched to flats
