I think there might be a little misunderstanding. I'm not talking about the Traveler Pro system that's built around a Nylon backplate (or a CF backplate for the Adventure Pro system). The products I'm talking about are stand alone wings: Eclipse or Traveler Pro. It seems that the only difference between these two stand alone wings is that the Eclipse requires a STA to be used with any kind of BP for single tanks, while the Traveler Pro has four slots allowing the use of a single tank without any additional STA (those being already built in the long / standard BPs), though it's still possible to use one to benefit from a weighted STA.
Regarding the BP, I'm not really sure because the kind of dives I'm planning to do is very diverse but I'll probably go for a stainless steel one first and I'll still be able to buy a second BP if I really need a very lightweight system for long travel and/or dives with very thin wetsuits.
So I suppose that if 40lb is enough for doubles, I could use a 20lb wing for single tank diving? Or is the 30lb wing better?
I'm still not sure about taking the course in doubles. I've never used those so it might be a little bit challenging to learn doubles + drysuit + all the fundamentals skills. I'm quite confident about my ability to learn, but that still represents a lot of new skills. Should I take it in doubles, I'd certainly buy an Evolve 40lb wing so.
There is an easy answer to your questions: don't buy, rent. Maybe the rental price is reduced during fundamentals, ask Marc.
If you don't buy, you'll have the possibility to try different equipment under the supervision of your instructor during the course, being almost sure that everything is set properly. You may also discover that doubles are not hard or, on the contrary, realize that they are not for you. You may learn many other things.
It's your choice in the end, but keep this option in mind.
