well it didn't take long for us to disagree on something :P
still, CTing an away game was to risky imo. Also, DMI (aaah, my favorite where i generally disagree with Joe) is an indication as to where the sublvls lie in terms of training & Gameshape. And unless i'm mistaken, the DMI heavely favored the hometeam. that aswell would have convinced me not to CT. i doubt you would have CTed in his position.
Also, i'm unfamiliar with saving enthusiasm, but i noticed that rainmakers never tried harder than his opponent in any of his league games, which would have put his enthusiasm higher than Quiquits one.
So after taking all that into consideration, i could say fairely that i wouldn't have CTed. i would have gambled on the fact that i would defeat him at home and take my chances against Obira or Sgolba afterwards, trying to win one of those games.
