Well genius’s its me again…It looks like I ruffled a couple of feathers fella’s.It was I who invented the bat tail and surfed it here at the banzai.You all can’t handle that(thats why you are hateing on me)…BB ,vector boof you all need to get your skill 100’s and learn how to shape again…four fin bat tail come on now!! that was just a plan ripp off of my design.For the record first bat tail ridden at pipeline by me in the early 70’s…ask jackie dunn or gerry…single fin to tri fin era it was my piloting and not any of you wanna be’s…gotta get back to the movie set see ya next time on that favoritte bat channel!!!
