I was thinking of introducing a handicap blitz tournament at our club. Has anyone got any experience of running one of these? If so, what handicaps did you use for the players ratings?

I found a poster for the "Welsh alternative handicap blitz" online at: https://plus.google.com/u/0/photos/101790193612326674671/albums/5962047843271460081
It looks like they had fun.
