I'm sorry to add a bit of confusion here, but I've to disagree with this. I'm definitely not saying I'm right, but I believe a quicker tempo would be more appropriate to a counter-attack tactic based.
The tiki takia is a POSSESSION based football, it means you want to build your attack and NOT rushing them. The ball moves between your players, and wait that there's a breach made in the opposite defense before starting the attack. You don't want to lose the ball in an inappropriate situation.
On the other hand, it's better to have quick defenders, to play in a high Defensive line. You want to make sure your possession is going to be in THEIR side of the field, and not a tone of useless passes at the back and in your own side. Pacey defenders because I'm not sure you'd like to get caught in a through ball, or a counter-attack from your opponents when you lose the ball.
Of course, the tactic success would depend on the rest of your settings as well (the good balance between this D-line, pass level, tempo, attacking mind, creative freedom...) and (obviously as my friend said in the previous thread) your players' attributes in the correct area
