I don't know much about insurance for private pilots, but commercially we were charged a lot less if the pilots had 2000 hours total and paid a loading till they had 100 hours on type. This is purely because of statistics with claims. So if you have 5000 hours and 10 on the 206, you would have a loading till you reached 100.
Perhaps you should negoiate with this hour requirement just like drivers ages with cars.
