Sorry I'm not buying it.
My planes stall the winch, with a smaller drum, I get to turn it.
We don't use light line anymore, so line speed isn't an issue. The line
creates the line speed by the amount it puts on the drum.
During the morning, a bigger drum makes sense, during the noon baloon,
2" or 1.75"
During wind 2" or 1.75"
Unless you have dead air ,or down wind the 2" - 1.75" drums will provide
a better launch on the line we use. I stall the winch, and have to push
it through to get it moving.

I must agree with Brian. My first winch used a two inch diameter
welded aluminum drum on a standard 12 volt Ford starter motor with a
12 volt battery. The two inch drum didn't produce enough line speed
to break lines so easy and we used much smaller lines. We finally
switched to larger drums when contestants began complaining about lack
of power for good zooms. What they were really complaining about was
the lack of line speeds. Unfortunately, the man who fabricated our
drums is no longer with us and we never found another fabricator who
could produce good welds and the end plates frequently broke. I still
have the winch I built in 1972 with the welded aluminum 2 inch drum.
We took it out last year and did a few launches and everybody was
amazed at how much softer and smoother the launches were when compared
to our standard winches. Maybe we should regulate the winch drum
diameter.

With all due respect I disagree Jeff.
At our local field when we launch to the north, it takes all the line
off the drum.. We get much softer, less powerful launches.. As
opposed to when we launch to the south we still have approximately
half the winch line left on the drum at the time of launch and the
launches are much more aggressive/powerful and all the broken lines
and broken models come at the south side.. Just My observations here
in Tullahoma.. Brian Smith

Charlie less drum diameter will lead to more line breaks. Since you
have more torque you can now crank more turns in and break the line
easier. -- Jeff Steifel
