I would have thought that there were rather too many tunes for one dance for comfort. Doesn't it make life complicated for the dancers geting used to one tune only to find another one coming at them before they've settled? Every tune has a slightly different rhythm - two's all I use in one dance, simply changing when the first gets to boring. I write not only as a fiddler, but also as a dancer.

NB: This is only my personal opinion and not to be taken as Gospel!
