IMO, there' s no technical reason why they can' t make a Mighty Mite Dually. Bowtech listened to many suggestions to come up with the 2004 line. If enough people would ask for a Mighty Mite Dually, they might just come up with one.
On the other hand, the performance gap between their Duallys and the I-cam bows seems to be shrinking. If there is a minimal performance advantage to buying a Dually, then Bowtech would probably only be producing that bow for a limited number of hard-core believers in twin cam superiority. I don' t know how many of those would really be short bow fans anyway.
That said, I still would like to see and shoot one.
