I really like the labella low tensions too.
Currently have Dunlop flats on my P and I'm really enjoying them. I'm playing/practicing a lot with a pick and the Dunlops sound and feel awesome. Really funky. Great fun!
It previously had D'addario nickel rounds on it 105-45 and didn't need the truss rod adjusting when I put on the Dunlops (same gauge). Not that I mind tweaking the trussrod if need be.
