One of the most popular sections of the GWTW Forum has long been the Swap Meet.  A great place to sell old, seldom flown kites or to get great deals on used (gently flown) kites.  Only registered users can see the Swap Meet section, let alone wheel and deal.  1000's (literally) of kites have changed hands thanks to the Swap Meet.

Some people might call them training wheels for kites.   

Helps with Yo-YOs and with enough wind, a Fade launch with the kite on its back nose pointing towards the pilot. Also, they keep tension on the leading edge portion of the kite's sail (IMO very helpful).

Does not help with the Twist aka Sleeping Beauty Launch unless you do a slight rock of the kite to get the nose off of the ground before the launch.

Other than that, another step to set-up and breaking down your kite.

The "slip-catch" is the little thingey on the roll bar that looks like a lead weight. It is supposed to "catch" the line if the kite starts to unroll too soon. Shown in the picture below:

Thanks everyone. So is the roll bar worth it?

For multiple roll ups it is a real help...A Talon without them wouldn't be the same for sure!

I think this was also called a 'yoyo cage' by Pim Kusters.  The idea was to keep the lines in the yoyo until you really gave an input to initiate the unroll.  You can do yo-slots without unrolling if you're good...this sort of thing. 

It looks like in the picture, the catches are a bit high off the LE, aren't they?  If the lines get to that point on the roll bar, you are already unrolling.

There are three different things being discussed here:

1/ Slip catches: Mark Clements uses these on the Talon and the Trident (as pictured by John). On the Trident they are a small cone glued along the roll bar - on the Talon they are a small peg that comes out of the leading edge connector for the roll bar (I own both these kites and I'm not sure these particular features do anything). The other kind of 'slip catchers' are small, secondary yo-yo stoppers placed beneath the main ones to catch the lines if you wrap the lines unevenly. These strike me as a very good idea but the only commercial kite I know that uses this is the Element (although I read about the idea from Lam many years ago) - they consist of a number of cable ties forming a ladder of secondary stops.

2/ Roll bars: A few kites have these (or their own version) - invented by Tim Benson (although it may have been Andy Wardley) for the Deep Space they also feature on Jest of Eve kites and a number of others. They are intended to make multiple yo-yo tricks more consistent and easier to achieve (they also work well with some of the more elaborate 'whilst wrapped up' tricks) - these do work well and nearly all my own kites use them.

3/ Roll cage: As stated below, designed by Pim it is intended to brace the sail when the kite is multiple wrapped. The Jest of Eve Trident also has this feature (this particular kite has EVERY feature and then some) - it works but adds weight to the kite and is rarely needed (even when the sail is really pinched).
