[24", 30", or 36" stands for pair of RB-5's?]

I have recently moved and I am pressed for space in my new apartment. I am forced to use my RB-5's as my main left and right which is complemented by the RC-3 center channel. My question is what speaker stand height do you reccommend to use with my RB-5's? I am looking to purchase Sanus Natural Foundations stands and can not decide on 24", 30" or 36" height. Any reccomendations?

Thanks.

Can anyone tell me where I can find the speker stands included in the attached pic? I am looking for a pair that will go with my cherry RB-5's,

Thanks.
