John (at least I think this is John Hawk), Ask Paul Rafferty. He owns one and loves it. I am technically "rated" on it, but can't tell you much other than I like it better than the regular Vector Tandem.
we just recieved the new sigma at my dz...i have been packing it since...the 2 of our instructors that have jumped it really like it, no ripcords to lose, easy to check reserve pin and cypress, easy to reach handles,and the best feature they like is that the main deployment handles are inactive until the drouge is out. the students that have come back for a second jump (first jump on vector or racer) said it was much more comfortable, the lower bellyband makes for better comfort on deployment.
from a packing point of view it packs easily, the closing pin setup with a pin on the drouge line took some getting used to. but this rig has my vote...
