I went with 22" sound organisation stands, and have been very pleased with the results. I checked lots of websites before purchasing, and while the consensus is to get stands that put the tweeter around ear height, there is absolutely no consensus as to whether to go a bit above or a bit below ear height if there is no perfect match.
So, the 22' stands were almost dead on with my ear height, but if anything, they are a bit higher. It sounds great, and I have not noticed any negative effect from switching from 20" stands which were a bit lower.
