Chad,
Too bad you didn't come to NCRC, I brought my sampler stash and could have given you a short primer.
Let me know, next time I am down caving with you guys I can bring some stuff.
In a nut shell, for caving I have mostly used the Fixe wedge, short for hand drilling and the double wedge when power drilling. I also used the Petzl wedge and some other stainless non climbing brand wedges. I have played with the triplex and plan to use them, but have not to date in a cave. Many friends still use the Petzl self drills for speed, lightweight and convenience, but I try not to.
I have also played with glue ins, but have not used them in a cave.
Check out these links I posted several years back. Do a search, the discussions still may be in the archives.
