These look interesting, does anyone here have one they use for fishing?

 

 

The people that have them love them.  Some of the love on social media is cult like.  I feel like the storage options are weak, and with modern, stable hull designs, this design isn't necessary.  I would have issues sitting in that straddling position all day.  If you were considering one, I highly recommend some seat time, and not just a quick spin.  I say that for any kayak purchase, but can't emphasize it enough for this one.

Saw them at a outdoor show. I agree with @J Francho, tough to be in that position for any long length of time. I'd try to find if the company does "demo days" where you can try them out. Contact any local dealers for any info on where you can try before you buy. 

Ball buster is my first impression after viewing them.
