Welcome to the GWTW Forum.
Guests (non-registered users) can view the forum but are unable to post.  If you don't have anything to say then why would you bother to register?
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.
There are several more benefits to being a registered user, but you'll have to join our little community to find out all the "secrets".

A couple of questions after re-reading some:

What changes did El Ronnie-O suggest to you? 

Did you use any mathematical design criteria for the delta wings, spreader location, leading edge spars, etc?

Most of Ron's help was in evaluating the flight behavior and a few build technique ideas.  He showed me several things to watch as it flies that I didn't think to look at that led me to adjust the dimensions and framing to get the balance right.  How it glides backwards, how to figure out the right bridle dimensions ,some of the ideas I took from dual lines that weren't necessary and actually complicates the build.  Nothing really specific on the design itself except for framing options.  I wasn't even sure the design would fly until he hopped in and helped get it up the first time.

I did use some basic rules of thumb starting out though.  SPreaders 15-20% from the nose end of the wings along the spine, rear wing 50-75% smaller than the main wing (came from Sauls Barrage kite and the cody) and adjust from there.  Pulled in ideas from all over to come  up with a rough formula for keel length x width vs wing size, wing dihedral limits and a few other things.  AS far as wing shape i just wanted to get kind of a fighter jet outline and the top profile of the f-22 raptor was my inspiration and I tweaked the look from there.  I did come up with a way to actually make the wing angle "active" and change with the wind speed and sail pressure instead of just relying on the flex in the rods.

WHen it comes to SLK's really the only limit is your imagination.  I've build a lot of SLK's over the years but all simple derivatives of diamonds, standard deltas, sleds or box kites.  THis is my first one combining different elements and a take on the "box delta" configuration.  All my patterns were measured and drawn out by hand since I still have a lot to learn about how to turn a 3d cad into a flat template.

You got it right:  Your imagination really is the only limit.  The rest is just details.   Cheesy

Here's a link to an album of kites that I've built - including quite a few of "my own concoctions" ( Wink ):

 Cool

Thanks with the info on the delta - I have a couple of delta derivatives on the drawing board myself, and I was kinda curious as to how important it is/was to adhere to the tested relationships published by Dan Leigh as you veer away from a "standard" delta design (talking in terms of leading edge spar length, spreader location, etc)

Yea I've seen alot of your work.  I love that sunburst color sauls barrage kite variation you did.  THere are some things you have to adhere to but its variable depending on how active or stable you want it. long and narrow is more stable than short and narrow, short and narrow with lots of wing glides well but won't park unless you have tons of tail, etc
