I march with the JSU Marching Southerners from AL...We are spinning them in our fall production...At first I really didn't like them but after spiing them for about a month or so I've come to like them in a weird way...haha but yea the rotations in the air do slow down so you have to work on the way you release so that you can get them out in the counts you need...basics are a somewhat different story to me...drop spins are feel the same way but double fast and singles are where they get a little weird...but that's pretty much the gist of the air blade...I like them in the fall but I don't really think they'll look good on the winterguard floor...sooo there's my opinion...
