I get frustrated when intro divers ask me to do a dive to thirds with them, with them in doubles. I won't do it. I also get frustrated when they want to do jumps with me. I won't do it. When I wanted to dive to thirds and do jumps, I ponied up the cash and took apprentice. When I honed my skills and wanted to make sure I had really mastered the basics of this cave diving thing, I took full cave. Now, I'm progressing and honing more advanced skills. It's taken a few years and a lot of time and money, and when divers want to jump right in and do advanced dives with me, it frustrates me.
I'd really like to do the Grand Traverse with some cave diving buddies of mine, including Netdoc, but after giving it a lot of thought I've decided that sort of dive will wait until they are Cave 2 or Full Cave. Plenty of other fun stuff to go dive, and you can learn a lot of the cave that you'll see on the Grand Traverse during those dives. That makes the dive, when you do it, much safer, for the reasons DeepSeaExplorer listed above.
