HELP: i have a chance to get Jecht Shot 2, need advice

okay, so i've been playing blitzball a lot, cuz i decided to go hardcore and get everything in the game...well, at least almost everything.

my team is somewhere between Godly and Decent, so i think they are Godlecent.

i've got...
LW: Tidus
RW: Wakka/Datto
M: Brother
LD: Ropp
RD: Naida
G: Kyou

i can beat every team in the league, but my problem is techcopying...other teams very rarely use good techniques, they only use passes and tackles mostly. tidus has none of his key techniques, and i just got Jecht Shot 2 as the first prize for the tournament. i beat the first two teams and am now in the third round with the kilika beasts (lol). i saved before this round though, and i am wondering what is the best way to get tidus' key techs? exhibition matches or league? and which teams carry his techs? you probably don't know the last one but any advice is appreciated.

thanks in advance

oh, and the tournament will stay where it is, right? so i can safely take a break from it to get tidus' key techs?
