Favorite Slim-headed DEs or SEs?

The RazoRock Game Changer has the slimmest head of all the razors that I have tried.

Razorock Lupo (aluminum)

Super Premium and super expensive:
1) Carbon CX (pretty much not available since they are never "in-stock")

Reasonably priced for the rest of us, and usually available:
1) Razorock Lupo Stainless Steel (slimmer profile than the aluminum version, due to cut corners)
2) Razorock Lupo Aluminum
3) Vintage Gillette Tech or modern Chinese Gillette Super Blue (same dimensions as most vintage Gillette Tech)
