Frankly, the most impressive I-boat was Ron Hunts' ship. The thing was impressive and showed what an i-boat could be ... and that was 3 - 4 years ago before shillings and whatnot.
Pat Clark had a good iBoat that he ran a couple years. Steve Reynolds got it and was spectacular in it. Tyler has a YouTube video of him on his channel. Brad Blankenship I think the channel is called. Watch it he's was the best iBoat captain I've seen, I saw Ron Hunt at Wades one year. Stangle would have gotten there too had he not moved to Ireland. I've been told that Frank or John Witsell ran an iBoat when they were a kid and were a pest to Finsters Yammer. They couldn't miss him and he could turn to catch them.
For those interested... here is the link to Tyler's videos on YouTube... because there are like 500 Brad Blankenships https://www.youtube.com/user/bradblankenship/videos
