The Muad-Dib looks kinda nice for freebase, my only concern would be cleaning it, maybe the 'burn off' and using the qtips/iso as suggested will clean it out nicely though, it sounds like it may have a steep learning curve but once you got it down it should be great.

I have a MFLB and while it would work nice with changa i wouldn't want to resign myself to never using it with cannabis again as it would ruin the taste for sure. Magic flight have stepped up since a few years ago, the new designs and cherry/walnut finishes are really nice.
