Thanks,

Which means that he was essentially flying at 11 lbs wingloading if the 80sq ft wing area listed on the Website is accurate. That's pretty amazing considering we rarely had more than 3-4kts of often broken lift. I never went with more than 9lbs in my LS8, and that was often too much. I know Chip didn't carry all of the water all the time, but still...
