Yep, it was me!
Diana - I've never really thought about why I do it this way, it was just something that someone suggested to me once that I tried and liked!
I guess if I try to think about it I'd say that I do it because the cards are telling you it's a pretty important issue, so I rethrow the spread to get more info, and use the majors to try to see the 'big' reasons for what's going on. Like, if the issue's that vital for me I want the more long term, indepth, intense view and the majors seem to give me that. I don't just want to know what's going on 'on the surface', or just beneath it.
Sorry, that doesn't make too much sense when I read back over it! Maybe we'll just have to stick with "I do it because I like it & coz it works for me!"
