I didn't think the two pickups were very similar from what I've read...
I've been through a couple sets of the Fralin singles, and they didn't work for me, very harsh sounding to me at the upper register.
There were some great things about the pickups though, clear and big sounding if that makes sense. The treble response was killing me though, I don't like to have my tone knob rolled off either for what that's worth.
I think the Dimarzio ultra's are stacked humbuckers in single coil housings, so I thought they were supposed to be a bit smoother.
My fav single is Jason Lollar, to the point where I'm ok with not trying any others (for the time being at least
)...
