Sky Soaring (outside of Chicago - http://skysoaring.com) has an L-19
that the tow pilots and glider drivers absolutely LOVE. It tows
anything to 3K AGL in 7-8 minutes flat. We have also did a dual tow
for fun and excitement - the tow pilot reported not much of a
difference from a single tow. I am on the board and insurance hasn't
been onerous.

That being said...

1) We have had quite a bit of maintenance on the ship over the last
year which we are able to do in house. I cannot speak to the question
if the L19 requires more maintenance and/or fuel than a Pawnee. If
you are really interested in the details on our maintenance history
please drop me a line and I will forward your contact info to our
maintenance chief.

2) We are actively looking for a second tow plane - specifically a
Pawnee (anyone know of one available?) - which we would use as the
primary tow plane while we determine which ship is "better".

My $0.04.
