I'm glad you're considering getting training to advance to the next level of diving for you! I've known some divers that have figured it out from reading, but that's dicey, you don't know what you may have missed. Technical diving has come a long ways this past 5 years. In the past many have gotten bent and worse and we learned from those mistakes.
Out here in the Monterey Bay area, we lost 7 divers this year. Almost without exception each death resulted from diving in conditions that were beyond the diver's ability combined with medical problems (like heart attack). I saw in a previous post that there was 15 knott winds and 5 foot swells and that it was not a diving day. I don't know if that means something different on the East coast, but out here, that's a pretty divable day. We've been out in 12 foot swells without that much difficulty, but you do have to know what you're doing though.
I think it best to learn from those before us, take classes from other well trained and experienced instructors. The competence you'll gain will all be worth it! I dove for over 25 years before getting some tech training and my only regret is that I didn't do it sooner.
