The Aimes apparently is a new model. I could not find much data on it when I Googled. One source I skimmed over indicated it was just introduced this month. It will be interesting to find out more information on this model. Terry probably has more accurate information than this, so stay tuned. As far as the 1.6 vs the 1.28, reports on this forum indicate the 1.28 work just fine, so I would not let that be a deciding factor in my selection.
