Are you going to take them with Danny? If so, you will get a good education along with the cards. As with any course, the instructor makes it or breaks it. Some just give cards, and barely have any knowledge other than what is in the text books, and others, do not even have to open a text to teach you how to uses gases. Main thing to remember, a TDI course is not a DIR course, and you can therefore expect to hear some contradictory information. Don't get into a pissing match with the instructor about, "isn't it better to do this" or the like, just take what they teach, and then follow your own path as you gain experience.
Keep in touch, and we can try to get you out on the boat either over the winter if you are game or next season. The damn weather has been painfull this fall. Been blown out for almost 2 months straight!!
dive safe,
