Not that i am THE Greatest at reading negatives.
But if the neg looks "Normal" i typically have the M at 20 on my Besseelr-45

Like you say, it is at least some place to start.

Oh Geez....what are then two types, Diffusion and Condenser.?
For B&W printing i find it easier to use my Non-Color head. But i like the way...the light system...of the color head prints.
I suppose it is like anything else...............if i did it long enough, i would get used to the condenser head enlarger.

For split printing it is arguably easier to use the slide in filters of the condenser head. But again, you adapt to cranking the knobs all the way instead. No big deal.
I am happy i have a darkroom with ANY Enlarger. :)
I cannot imagine shooting film without one.

Anyway...............Thanks Again for the replies.
I Appreciate It.
