SN-10 vs CAI 302

Hi,

I have been using a SN-10B/Volkslogger combination in my LS-4 for the
last 5 years and have loved it. However, I just acquired a glider with
a CAI-302/PDA combination and am contemplating swapping the systems
before selling my LS-4.

I like the presumed flexibiity of taking the PDA with me at the end of
the day, having the flight log on the SD card as opposed to having to
upload to a laptop, and having the option of running different flight
software on the PDA. I also like the idea of having it with me at the
pilot's meeting and being able to set up the task and/or do what-ifs
for AATs without having to be at the glider.

However, I'm not sure about giving up the SN-10's simplicity and its
superior (I think) wind calculations.

At the risk of starting a religious war, I would like input on the
strengths/weaknesses of the CAI-302/PDA (running GPS Glide Navigator II
or similar) for competition use as compared to the SN-10, especially
from those of you who have used both for competitions.

TIA,

Frank
