i feel safer, and prefer to self launch.. after driving 20 k's over the limit to get to the beach ,run up and back to sort out lines, grumbling and swearing to myself i am gonna trade my inflatables in for foils so i can get out faster, i just don't have patience to wait around for anyone else to give me a launch!!!
sounds like some of the guys on your beach are in a hurry too to get out

it has on occasions ended in tears for the kiter thats been too keen!
only suggestion that comes to mind to slow down your assisted launching issue is , when your the assistant, do the thumbs sign and wait until its replied in same... so keep thumbing until the guys on your beach realize you wont let go of their kite until they reply...
