I gather there wasn't any handicap in the last tournament. Personally I would be happy playing with some sort of reduced handicap. I would suggest Handicap-4 stones, this is two stones harsher than the European Norm, but given the duration of the tournament I think wisely so.
Example 3k plays 4k - no handicap Example 3k plays 8k - no komi
Reduced handicap sounds good. If you use normal handicap, then theoretically you have 0.5 probability of winning. This would not do for a tournament.
