I might be a 'stick in the mud' and old fashioned helo instructor but I believe that for ab-initio helo training should be in a simple single engine helo where the thrills of helicopter dynamics can be trully experienced unencumbered with all the bells and whistles that the 109 has to offer. The A109 makes for a good intermediary (advanced) trainer prior to progressing to larger similar helos. Oh I fly and instruct on the A109E & S.
