I did a search for Quad Handles & didn't come up with much, so here goes.
I just got a pair of SUL handles. I haven't had a chance to take em for a test drive yet.
PLEASE, explain to me what's going on with these babies. Are the longer bottoms going to give me greater angle on my Rev? I'm sure you understand what I'm asking. My leading edge being closer to me, bottom of the sail farther away, GIVING THE KITE MORE LIFT?

?
My 2nd question is: Why can't these handles be used on a Std or Vented???
Thanks Again

The SUL handles are 15 inches long (measured along the tubing from end to end, not across the D-clips) ... they are said to improve low wind flying by giving larger deflections to the kite for normal hand movements. The 15 inch handles, by yielding larger kite deflections, yield a more twitchy kite as the wind speed increases. The standard handles are 13 inches long and seem to be a good compromise for most folks ... even on SUL kites. The Rev II (about 80% the size of your SUL kite) comes with 11 inch handles to make it less twitchy and more controllable. Again, many fliers use 13 inch handles on the Rev II.
Paul McMasters uses custom made 17 inch handles (measured across the gap ... must be about 19 inches along the tube)for the majority of his flying. He's in an extremely low wind area for most of the year and claims that they really help.
I have some four foot Rev-like kites and made a set of 9 inch handles to calm them down. I don't like the feel of the 9 inch handles, so instead use 11 inch handles for these kites.
So, although most fliers use the 13 inch handles, there are others who use the longer handles at least part time. Nothing wrong with using any standard handle on any standard Rev kite. Mix up your kites and your handles and see what appeals to your style of flying.
There is no one right answer ... just use what you're comfortable with and what helps you fly better.Don't use standard handles on the Blast series though ... they're not strong enough.
Please come back and tell us what you think after trying out the handles for awhile.
Cheers,
