@dudemanspecial 's advice will get you in the game.
There is no right answer, however. It depends on the presentation you need and conditions. I am not always tight, for example. That is limiting, and the mono rig is not designed to be limiting.
It would be better to tie 3 patterns like walts, frenchie, and perdigon (or whatever your confidence patterns are) in several weights and hook sizes.
For example, water is low AF right now in NEPA, so for me to catch fish yesterday, I was throwing the lightest tungsten bead possible (that pairs correctly with the size hook, of course).
I hate shot, so I carry extra tungsten beads to slide on the line. That makes the point of contact the fly. I can fish a size 16 perdigon or frenchie in 4 feet of heavier water by adding another 2.8 mm to the mix without changing the size of the fly that is working.
Tightlining in heavy water, yes, you want heavy flies to get down in the zone quickly. But in low water, quiet runs and slicks, you don't want 1) the big bead making noise as it enters the water with a plop, and 2) sometimes you want a slow fall not a quick descent to the bottom.
