OK, so today I practiced standing up with a strap. First time in a long time. Boy did I stink. Anyway, I don't hang my bass (Zon) any higher or lower than I have my previous basses. Both hands are comfortable and not in any pain. However, if I let the bass be (with no hand on it) it goes neck heavy. Well no Zon I have ever played has been neck heavy. Then a friend of mine says, "You need a new strap, nylon sucks." I'm using an Ernie Ball nylon strap. My friend suggested Levi's leather. Should I just adjust my strap? (tighter or looser?) What do you all think?
