To recap how Triples works: there are three players on each end of court forming a triangle - one at the T, and two at the baseline where the singles sideline intersects with the baseline. Players self-feed with a bounce feed. Both sides rotate one position after every point. Full court (including alleys) is played. First team to X wins.
Using a slower ball on a full 78-foot court introduces a fitness element. Having the players self-feed introduces a strategy and directional control element.
The article did not give details about who feeds or how, other than suggesting players feed rather than coaches. When we play regular Triples, I usually feed straight ahead to the player across the net from me at the deuce side baseline. We play first to X, best two out of three, and the players rotate positions after every point, so someone new is always getting the feed. I suggest a similar strategy here so that a different person is serving every point. So consider whomever has rotated into the deuce side baseline position the feeder. Avoid having the player at the T as feeder.
As for scorekeeping, because you are rotating players after every point, I would go with a 'first to X' or rather than a traditional 15-30-40 scoring method. If using a 'first to X' scoring strategy, alternate teams feeding with each new game. If you want to play timed rounds, you don't need to have an end point to the game. Whichever team has the most points at the end of the timed round, wins. But with this scoring strategy, you may want to alternate which team is feeding with every point, so that one team is not feeding the entire timed round.
No need to organize a big tournament to enjoy this activity. Consider using this as a warm-up if you have six or more players in your group. If more than six, that's fine - just have the extras rotating in since there is a rotation after every point and things move pretty quickly.
