I was told the BK117 TT straps had the same part no as B206L TT straps - I was told they where the same item - only without the need to change every 2yrs on calendar time? I did have my doubts - anybody know if this is the case? I wouldn't have thought the 105 straps where very different to 117 same head etc. If they are the same - you wouldn't have any problem finding straps - so I guess that kind of answers the question.
