The reason I didn't choose the Tribalance was the cost, weight and difficulty in turning. Also without the outriggers how
stable is the Tribalance. I tried out the Pungo, Loon 138 and Perception America before I settled on my Necky Santa Cruz.
Of all the yaks I tested the people at Charles River Kayak said that the Santa Cruz is the most seaworthy. When choosing my yak I talked to kayakers and got their input. I errered on the side of safety.
