Word on the street is that MX109 (aka The Woodymaker) might be coming back. I’d love to get my filthy paws on that! 
But just in general, tisha has mentioned the old Alpha Female Series, Sunshine Series, and Drive Him Crazy series (of which I guess MX109 is one). I’d love to try any of those, especially the Sunshine Series. I don’t seem to do well with TAH, so I’d love a “happy” mix that is not MX135.
