I would be curious to to know as well. I just got a new RMR 14'er raft last month and have already used it three times. It's a heavy bastard for sure but the quality/engineering seems to be good with the price point being the selling/buying advantage. I would like to hear about their IK's though!
I picked my raft up for a great deal from: DRL River Gypsies "Home"
or phone @ 541-979-5646. He's a great guy to talk to. He sell's boats on the side and pretty straight forward. I don't think he would push any product he didn't think was right for you and may have some answers for you.
