Robert, blind 3,s is a bit more involved. practice landing blind first of course a nice trick in its own right. leaving the blind spin late and just wake to wake is the key. start making handle passes sooner rather than after landing. Because there are opposite forces involved in blind tricks its not just spin to initiate.
go up, initiate the blind 180 passing the handle which now is your back hand on the second 180. to initiate the last 180 push the handle to your front hip, or knee whilst looking for the boat.
reading the comments seems tro be for a regular 3 and not blind?
hope this makes sense
