This would have helped me in my Tech 1. In the end, it cost me a fair bit extra in time and money and frustration. However, sometimes it is not possible to have a dedicated buddy to take the course with and you have to take your chances.
I think I am happy enough with our hashing out of the issues in this thread, that I'm going to walk away, but I wanted to touch on this one quote first.
When I was in the throws of deciding what I was going to do with GUE going forward, I turned down more than one request to sign-on with divers that were not my main/only buddy, but whom I did know.
I think after you realize what it takes to be a quality team, you really can't expect to go in with an unknown and make it happen like you should. It's just too much potential frustration.
Maybe this is just me, but I'd rather completely sit out if my buddy can't show, and I sure as heck wouldn't have walked into a GUE tech or cave class without him, a well known quantity.
To me it seems almost pointless not to share the growing experience with someone that you will be diving with on a continual basis.
Maybe I just like to avoid the annoying issue of being unpleasantly surprised.
