Glen,
I had a set of 1900's a few years ago, Keith Strange told me that ALOT of performance gets left on the table with Aquas because they really don't have a hydro booster on the bottoms, more just a piece of angle aluminum material????
I asked him how much difference it would make if one was to install a real booster like on the PK floats and he said "ALOT"......... It looked to me like their booster might fit right over their "right angle booster" and if it wouldn't; a minute to grind it down till it would...... For any of us that can remember how doggie Edo 1400's were on 95 Cubs until the boosters were installed (day/nite) I would expect
the same if the Aquas; had real boosters , of course most noticable if your heavy, its hot, high humidity,or flat calm; but that's just an opinion.

P.S. As you can hear in video that 0200 is getting after it, the pilot has been flying floats, since he was weaned off breast milk.
