Just had a look at my sail log from the last two years.
2016 was light wind, only used 7.7m and weed fin.
2017 was moderate wind used 7.7m 3 times and 7.0 once, half the time on weedy and half pointer.
From memory there is weed but not a huge amount. I think most folk used pointers.
The lake is mostly fresh water and the lack of buoyancy is surprisingly noticeable.
