I purchased the ULI to mostly paddle through rocky areas in a class II and III river. The nice thing is the board also handles well in flatwater and, of course, surf. In fact, the most fun I had on the board was in modest East Coast surf in Myrtle Beach. I found the board to be fun, but as I gained weight (about 250 lbs), I found that I really wished I had bought a standard (non-inflatable) SUP. My son loved this board, and anybody under 200 lbs can easily inflate this board to enough pressure that it feels nearly as firm as a solid board. However, heavyweights are going to be able to feel the flex that comes with an inflatable in spite of the fact the ULI boards can handle significantly more inflated pressure than any competitor in the industry.
In summary: Great board, nice that it can be deflated and stored, super strong body even on sharp river rocks, just be under 200 lbs or prepared to feel the flex.
