I fly fish for hours in the salt marshes and in the rivers . Today I was on the water from 8:45 AM to 4:00 PM ...no lunch. I was in a 135 Ride and I would have to say ...Give Me My Manta Back!!! The 135 is a great yak but the seat is not! I thought I'd try my sons yak while he is in Iraq. The Manta is the best as far as seating and a great yak all around! Not too good for standing up in though like the 135 is.
