I have a Superfly and love it, but if I were doing a thru I'd likely pick up an Edge or Tadpole... The SF is an aircraft hanger and I just can't see myself needing all of that under AT thru circumstances.
I bought the SF, since it was the better all around choice, but some day I'd like a minimalist tarp for fast paced summer trips. If you can afford for the minimalist one to be cuben then you're talking stupid light. That'd be ideal for the AT, I think.
One thing to keep in mind; most anything you buy from our lovely cottage vendors will be worth what you paid as long as you take care of it. You really only stand to lose shipping.
