Eric,

I also use several redundant systems in my ventus. Sage, B50, B2000 &
WinPilot PRO. I used WinPilot PRO for Tasking , climb maximizer and
navigation, marking lift (lift dots), wind, final glide etc, the B50
for speed to fly (sound etc.) climb. Sage as a back up. ( I haven't
need it, but is does match the B50.) I set the B2000 for alternate
airports & landing fields in the area that I am flying and a check on
the Wind Calcs and final glide.
