My dealer in Taiwan had a Speedball for demo so I took it on a 15 minute spin.
The board is extremely fun. It does not excel in any single category, because there is no category for horsing around, mixing it up between styles and just having a good time.
It was very easy to ride (I read in another review that it was skatey - not at all? Maybe if you have a habit of weighting your back foot a lot, I'm more of a 50/50 Mako or surfboard rider, and I felt it was totally solid). It took me about 1 minute to dial it in and have fun.
Planing, acceleration, speed and upwind are excellent especially considering it was the wrong size form me - it was a W16 and I'mm 90Kg marginally powered up at the time, I was as fast as the rest of the boys and going upwind same angle without any particular effort.
Pop was good - better than my Shinn Dundee - and landings soft. Carving/tight turning was fantastic - much better than the Dundee for me (I have the 44cm Dundee) and the Mako 150. Great comfort and the new straps have an advantage over 2012 - you can adjust the duck angle. Stiffer than the Dundee. I could not feel the small chop at all - maybe a similar "air cushion" effect as the Monk??
Overall I'll stick with my Dundee because I'm more interested in waveriding (especially riding the crappy waves / mutant chop we have here...) and I feel the Dundee suits me better for this (flex, glide on wave power without kite pull), but for balls-out fun mix-it-up all-terrain this is the best board I've been on.
