That's odd.  I've had my Rev II for a year now, have flown it in winds ranging
as high as 25, and have never broken a spar.  And I've had *plenty* of ground
contact with it.  The Rev II is framed with Advantage 3-wrap (the Rev I is
framed with 5-wrap) and is surprisingly sturdy (as compared to a delta framed
with 2-wrap).

You're not going to find something that's less brittle than Advantage and
not heavier--that's the whole point of the spars.  It's extremely stiff and
and extremely light.  The best compromise may be an Easton composite such
as 3/30.

When I referred to the AFC 1960, I was talking about ultralight deltas.  The
Rev II is by no stretch of the imagination an ultralight kite, though there
is a 2-wrap ultralight kit for it.

The .1960 is not nearly stiff enough for a Rev and you're likely to break it
in a crash.  You might try a heavier AFC, such .2300 or .2400.  These can
be ordered from Into the Wind, Hang-'em High, or High Fly.
