Fished a few hours this morning with my Melenium B300 Palma Horse seat.
It is the most comfortable seat I have EVER used in my life! Stradling it, while sitting feels so natural, and it serves as a great leaning post too. I heard a couple guys say that it spins a bit while running, but I did not have that issue at all, even at WOT. It stayed motionless.
I will never use any other type seat again!
