i was just wonder what is your favorite body material. i use glo yarn but it isnt what i was wanting.
McFly Foam is a definite improvement over glo yarn. I’ve read that Egg Foo Yarn is even better but never tried it.
I go abotu 50/50 with the eggfoo and mcfly I like both and they both have a color or two that the other doesn’t. If you dye any of your own use the mcfly the eggfoo does not take to dye as well and tends to come out spotty even after a good degreasing… I really don’t know why but it always happens to me when I try to dye a good lavender on eggfoo and never have a problem with the mcfly just right out of the package with no rinse. Glo yarn has it’s place and is really a ton of fun to play with for things like wool head sculpins and such if you have it on hand but for glow balls and egg patterns I don’t like it.

I use one color of the original glo-bug yarn for the couple hundred a year that I tie. Works fine, easy to use, fish eat em up, so I stopped innovating about ten years ago.
McFly Foam is the favorite here… I tie hundreds of glo-bugs… At least they are only 15 second flies (literally) to tie. A friend is a Kenai River guide and literally goes through a couple thousand every year in his business, but has them down to 8 seconds!
Cannot imagine needing more colors than they produce! 
There is a whole full of colors most places…

Have you ever seen a lavender (really soft purple) Hap? Not to hijack the thread just curious, I use them with incredible success over almost any other color and if I could purchase it that color I would love to.

Jerry Garcias work great, especially on jaded fish… I doubt I would get sideways with a particular color… But since I have not seen the lavendar stuff I may be missing the great deal???
I do have purple and royal blue… Maybe a mix of white to lighten it up… Comb some togather and see what it looks like… Nah! I can handle the 25 or so colors I already have!
I think I would shoot myself or end up in a rubber room if I had to tie 2000 of anything

Looking at their color chart:
It looks like 33-January is about as close as it gets to a very light pink-purple hue. Alternately, you could try using the 41-purple McFly foam as a dot in a cream glo-bug yarn main body, or make a 41-purple egg with heavy veiling.
I use #41 purple and tie it extra heavy then trip to an oval and us it as a mulberry for Carp.
And if you saok them in a little floatant they float just like a mulberry as well!!! I have #41 and it’s just to dark, what I am dying is a very soft pastel like lavender… not an issue just my idiot nature… I have a tendancy do do everything the hardest way possible.

I’ve always use the Glo-Bug yarn. I guess I’ll have to try some McFly foam, soon.
I have both Glo bug yarn and McFly foam. The McFly is much easier to tye the micro eggs with. Haven’t really tried the larger eggs though.

Egg Foo Yarn http://www.wapsifly.com/eyf.html
I’ve seen that tying sequence before, and the simplicity is indeed impressive. I have never tried it, but it would seem that for every 1" of material, you’re throwing away 7/8"?
Egg Foo Yarn is a joke, IMO&E. It takes much more time, does not flare nearly as well, costs more and is far less flexible in the sizes you can tie with it.
For a glo-bug all you do is start your thread, Place a properly sized segment of yarn on top in a soft loop. Pull the long end of the yarn until the clipped end of the yarn bundle is in the exact right spot. Apply three more wraps of thread atop the soft loop, then three or four around the thread holding the yarn on. (Between the hook and the yarn)
Now whip finish and glue. Both ends of the yarn are now held straight up above the hook and clipped straight across one time. Keep it straight and level.
Now fluff up the egg… Or just toss it in the box until it is time to fish it…
Literally a 15-second fly and it is extremely effective.

Edit to add there is no waste as the yarn is dragged to exactly the right length and the long end is trimmed to match. The first and last egg may waste a trace of yarn, but it is not a big deal.
Now see, hap, even a fly as simple as a glo-bug gets tied in different ways. 
I use a doubled piece of yarn instead of a single piece. And while there is a little waste, it is not enough to worry about. And I tend to whittle on mine to make them round, which I can do while chatting on here. Not that the fish care.

I think I’m with you, but pics of at least the key points would be helpful.
