Always pre EQ if going to the PA for myself. In my experience, a lot of venues prefer that.
Reason being, they can get a good sound out front and you can have a different stage sound which allows you to cut through better. Win-win.
I would say Lo-Riders are better suited for yourself if you require the 40 G.
Hi-Beams and Fat Beams are low tension with a 40 gauge so that may not work for yourself, especially with a floppy B string.
