I just want to say thanks to everyone contributing info in this section, I gained a lot of useful tips from this site and my first split attempt is complete, I couldn't be happier with the outcome!!
The board fits so tight with this set up, the flex is as stiff, possibly a little stiffer when in ride mode. Torisionally, the board doesn't seperate at all when i'm strapped in just standing on carpet flexing it. Highly reccomend the karakoram set up!
