IF Reach is real and now. Hopefully people that backed Helix won't
be part of those folks that never got anything for their money:

I would just sit and wait till a real Helix shows up; if ever. Also;
during initial marketing - a lot of promises in regards to weight & sizes
will be made. Then after the research & development phase; those
numbers may change.
