Well this is an old discussion but a year down the track and all of it on the Kipuna I have to say I'm having soo much fun!!
I jumped on my TT Cab custom 133 for the first time yesterday in about 12 months - and it wasn't nice!! ( but it is a great board!!)
The U'D kipuna is a great fun board on both flat water and out off the beach - cant fault it really (but be aware I'm not a surfer before kitesurfing) . I'm into boosting often and (touch wood) is showing no signs of it abuse!
I see underground have a new look board of the same tech and of course Axis have a similar board (not sure what the difference between the two might be?)
Best thing for me is the 'ease on the kneeze' with this board - comfortable for hours on the water. Just thought I'd share my experience!
If I manage to break this one I will be looking for a replacement ASAP!!
