I just ran the numbers for the Ventus B again. With no water the 16.6M
is better up to about 115 mph. With full water the 16.6M is better up
to about 125 mph.

I fly with winglets on my 16.6M tips and the plane flys much nicer than
the 15M with winglets. I am looking forward to running against an
other Ventus B this summer to compare the polars.
