And we so have to have a go at a toss and catch of a stack, well toss maybe...... Over to you Jonesey.
Back in '92-'93, I used to catch and throw a progressive stack of Rev I and II (this was before the 1.5 was introduced). The throw was pretty easy -- just stack up the kites with the II pushed to the edge of the I and do a normal toss. The catch was a lot trickier, but definitely possible with two kites. I'm not sure I would have tried catching 3, though.
