amateur Canadian research baker hoping for ideas

Hi all. I've raised 5 children with a lot of help from a bread machine, and am always trying new things. Now I'm an empty nester with only one mouth to eat the results, so progress is a bit slower. My blog is at http://johnsankey.ca/bread.html with a new one on international breadmaker breads at http://johnsankey.ca/breadi.html . Right now I'm trying to figure out exactly why bananas and raw Canadian potatos are duds, so will be trying the ingredients forum to start.
