I own the 6'2 2025 model 88 liters.
Have only tried it parawinging - it gets going pretty fast but definitely not as fast as my downwind board of 115 liters. Could be a technique issue on my sides
it feels like a tiny board and construction looks very good in my opinion. Light weight but solid. Deck pads are high quality. The board feels very nimble after a DW board.
whether a 6'6 is a good board for an inland lake totally depends on your weight, the foils you are using, etc. I would say my 88l is the ideal killer quiver that covers high winds up to 30 knots with normal wing and parawing and down to 12 knots (with a LEI wing, not parawing) for me:
If you are thinking of Foil driving with the board - FORGET IT! Signal is terrible through the board!
