well i really think it is to early to tell who will make the biggest jump, but if i had to choose corps to make some type of an impact they would have to be Citations and HYPE.
citations made a big jump in 2005 from 2004 in Div III from placing second to last to just missing semis in 2005 to making semis in 2006. and who knows what will happen in 2007.
i will agree w/ my corps mate from citations we did beat out hype .45 but that was last year anything could happen this year and i think its still to eary to tell who is gona come out on top. by the end of June i think it will be ovious who is gona be gunning for the top spot.
