Do it. The busman 660 sounds fantastic. I had both of the pieces of gear that you referece and I liked the 660 more. Super sound, super transparent. Nice lights. Yes, it's VERY lightweight. The only thing special that you want to know is that you do need to run it 100% of the time with the -20db pad engaged. I assume you're considering the low priced one in the YS. If I had an extra $350 laying around, there's no doubt that I'd have already picked that up because of the size and sound.
