Enjoy! I like the idea of ordering multiple samples from the same house to start getting a 'feel' for the house. When possible now, I try to obtain as many samples from a house at once.
My favorite among your list is PG Cadjmere - it's a great woodsy/gourmand. My least fave is Sushi Imperiale, which I found to be unpleasant. I have those Frapin samples, and though they were good fragrances they weren't my thing. Right now I'm working through the Farmacita fragrances, though I haven't tried Sofron yet (I recommend Chia, Cara, Ambra Nera, and Indonesian Patchouli).
The next time your order samples from LS, some houses you should consider sampling from are Profumum and Mazzolari (high-end Italian), Montale (middle-eastern style interpreted by French perfumer), Stephanie de Saint-Aignan (super-niche French), and Parfums Delrae (small US/French house).
