doublevr Current pre-production prototype is going to trash along with the team behind it.
...oh balls, what a shame, i'm so sorry, still i hope it's all valuable experience. Though in some way i'm glad you're rethinking the entire concept, there's been some interesting new tech recently, at least one Handy copy, and don't get me started on that bunch from Hong Kong with their hyper-aggressive marketing and the weird cult. The field is moving fast, may as well aim high.
So, how far back are you going, design wise? Still [up/down] and [twist], or are you rethinking from the ground up? Because i'm gonna pitch it now, it would be amazing if you could do suction. Suction is like the fourth dimension of axis; all axis of movement are just motions, but suction is an organic effect that adds a huge colour palette to that/those motion/s. If you could conquer suction with Mk2 machine, you would have your own cult! And lots of money.
Been using an open loop suction machine / Handy hybrid for years, i honestly can't imagine how y'all cope with 'just a sleeve'. Best feeling in the world, and nobody is marketing it yet....
