The I20 mast is thick, especially above the hound and the I20 kite is huge compared to the HT kite. My concern would be what would happen if Bach is out having fun with 3 on board (which he does), flying the kite in sporty winds, stuffs a wave, and the mast is not in the best rotation??

Typically the I20 mast survives this. Not sure the HT mast would. Will he have to re-position the spin hound and mast hound on the HT mast, and what affect will that have?

Great discussion, but looks like he will need to find another carbon I20 stick, to complement his investment in new sails.
