Walter, I'm familiar with your recordings, and don't know if we have the same processing needs, but FWIW re the Waves Masters bundle, the particular things I like about it are:
The LinEQ's low freq filter does something really nice to the sound just by being turned on, whether boosting or cutting, and whether in bell or shelf mode. I never use more than 2-3 dB change. I rarely use the EQ actually, and almost never use it on anything above 1 kHz.
The Lin multiband is fantastic for taming overly active dynamics in the low end and low mids. I use it very gently and to my ear it works without doing anything bad to the sound. Setting the crossover points is everything though. Occasionally I want to reduce the upper mids on a file and I like the sound of the multiband for that better than the lin EQ.
The L2 is kind of failsafe. As long as I don't ask it to do more than 2-3 dB of gain reduction, it also doesn't do anything bad to the sound, just controls the level. I like the sound of its dithering and use it always for that.
