Billy,
As variety is the spice etc a possible variation would be Dunoon, Tignabruaich, Otter Ferry, Stachur, Ardentinny, Dunnon. About 75 miles 3000ft climbing ( misses C11 climb !). This takes in the beautiful rolling road along Loch Fyne. Possible cafe stops at Tigna or Stachur. Route on map my ride http://www.mapmyride.com/route/gb/argyl ... 3639394851 - dont know how to make this a link !
