I confess that I am a bit of a collector when it comes to plugin compressors. And if there's one of those I had to keep, it would be this collection. I bought on release and I still think it's sensational. Way more versatile than say the 1176/dbx/la2a, etc clones.
I use it everyday. And btw, I do sometimes like it on the master buss. Not every time, but in the right production it's killer :)
I can't remember off the top of my head mate. I'd imagine it was an upbeat breakbeat-style production, where the CL1 could react much faster to the fast grooves than your typical SSL, or other buss comp. You're right though, it does have a certain character and it all depends whether you want to be that drastic on the master buss, and whether it sounds good on the production.
Thanks for the comment on Reinjection. I rushed that a little, so I appreciate the positive feedback :)
