Well, the class might be less enjoyable, but if you'd learn more... I do agree there would be no point if you know with near certainty that you will never use doubles, but I think a lot of singles divers fall into the grey area where they don't really know whether they'll use doubles at some point in the future.
I'm only speaking from my own perspective having just taken the class. If I say anything that may be off, I'm sure someone with more experience and knowledge will correct my errors.
I plan on diving doubles again in the future as well as advancing through the Cave and Tech classes that GUE has to offer. I'm very excited about moving forward in with my dive education. However, I'm not in a hurry to rush to the next level. I'm very much enjoying the journey.
One of the concepts that I got out of this weekend is that of using "building blocks" to further my knowledge and build a solid foundation for my diving in the future.
I'm glad that I took this class in a single tank.
I have enough to work on without introducing one more thing I have to concentrate on. When I get each of the skills sorted out and they become second nature, then I'll add more to the mix. I feel that when I get to the point where I don't have to concentrate so much on the basics of buoyancy, trim, propulsion and planning that I can then start to add things like doubles to a more solid base of skills.
In my opinion, until I have these basic skills up to the standard that our GUE instructors expect, I have no business trying to move on to anything more complicated.
Keep in mind that everyone starts out on this path at a different level of competency, so if someone already has already built a solid base of competency in the basics before entering the class, then by all means I don't want to discourage them from taking this class in doubles.
Just my opinion at this time. I may think differently about all of this as I learn more.
