Bit of advice?

Haven't played Angband for a loooong while, now picked it again...

Playing 3.3.0 Vanilla, HE ranger, currently hanging around 1600' looking for stat potions. I'm kinda overpowered for this depth, but I'm afraid to dive as I don't have poison res and my CON is bad (I have around 230 HP at the moment). On the other hand, I have the basic four resistances, FA, +10 speed, and decent damage output. I have blindness resistance, but no confusion resistance.

Given that I feel noobish and go slowly and carefully, does it make sense for me to dive deeper? Essentially, I'm afraid of the "It breathes... you die" scenario and I don't want to be bothered to cast detect monsters every couple of steps until I get considerably deeper.

As an aside, got my first "omens of death" level yesterday -- after very carefully creeping around it turned out to be a vault with Balrog of Moria + escorts, a great storm wyrm (level 67), a few mature dragons, and other assorted fauna. Balrog at 1600'? Ah, thankyouverymuch, could you point me to the nearest stairs, please..? :-)
