Thanks! Yeah, I will probably get Thunderwolves in the future, but I don't think I will get to be using them in 30k, though. However, since I came to the conclusion that I have more fun painting 30k than 40k Space Wolves colours, I will probably paint all my Space Wolves in the 30k colours now.
I also feel like that I'm one of the few peoples on the planet who are not offended by by the notion of Space Wolves riding giant wolves. To me they were always a bit more on the mythical side than the other legions and chapters. As for individuality, I actually tried to tone it down for 30k, because I feel that 40k has overdone it too much.
As for my current plans; I think I should paint another 15 Marines before moving on to the Terminators.
