ARC/ foil kites.
no pump, fast set up, fast package, bomb proof, easy repairs, no bladder leaking/reparation cost. can be used for years,saving money.
waterstart: ARC have their autozenith feature, u drop the bar, the kite will usually (85-90%) go back to the zenith depowered.
for true beginners , for one LEI waterstart, u usually do 3/4 waterstart with an ARC because u dont spend some time to relaunch the kite. u dont have to focus on controlling the kite since it will be parked at the zenith depowered. if u have waves +current, u can just focus to put your board on, without forced to control the kite as well. once your board put, u can pick the bar and focus on the waterstart. one thing at a time. as a beginner, u WANT to get on the board as fast as u can, so more attempts = better (now as a school, u might want to slower their progression and stay with LEIs, some have that mentality, sadly, but i can understand that schools want to make money..)
ie: "LOL, nahhh i stay on my LEI, so if they cant manage to waterstart, they can still take another lesson, if they pick an ARC, they might waterstart fast enough to not take another lesson"
= that was epic, i was astonished.......and i heard from other beginners that some schools had that mentality......
intermediate riders: ARC have given them the reflexes to drop the bar instead to grab it like hell ( many peeps still do that...pullllll alll theee barrr in, increasing the problems), they will know how to launch alone, land alone, land/launch any type of kites and can pick LEI, ARC or foils depending their preferences.
relaunches: it s good to have some ARC, foil, a LEI and a 5th line LEI so peeps could have some clue how to relaunch different type of kites, despite most of them are relaunched while pulling a rear lines, the different type of riding and controls. u dont ride a bow like a delta or a C-shape. foils are usually relaunched faster than LEI, ARC pretty much as fast as LEI if u managed to drop them.
downside: keeping an open minded mentality is the hardest part. not being a Lemming and following everyone is a hard path...but you can have LEIs,ARC,foils in your schools.
i learnt on LEI (modern LEIs), i ride some LEIs, i own a foil and an ARC. if i could have learnt with an ARC, my learning progression would have been increased by a LOT, because fighting the waves+current+controling that stupid kite pissed me off a LOT.
