Hi Colas, a great experiment I have a Hipster Twin which I love and recently added an Infinity Escape Pod. The E.P is so fast and has that friction free feel on a wave, the thing that surprised me the most was how solid it feels on my backhand. Not a true twin and a little challenging for me with my height and weight at 6'3 and 100 kg riding the 7'10 E.P.
Where you inspired by the Harley Ingleby HIBT 3+3?

Cheers.
Steve.
