"We may have struggled before Christmas but this competition has been like a new start for us. It's more dynamic and exciting. It's a chance to free your arms when you are batting and really attack with the ball.
"It would mean a lot to this club if we could pick up that silverware."
However the odds favour the Indians and Lake Taupo CC to meet in the big final on recent form - with both also unbeaten in the T20 competition.
