Not had a great deal of Menthol experience, but B&M Artique melts your face off... Nannys Ice and Slice is very very nice, maybe not strong enough for Menth heads though...
TFS Subzero and Traditional Menthol, very weak.
Fitjar Folgefonn, again I found fairly weak...
Fine Snake bite has a nice balance.
Alcolado Glacial A/S is superb, nice and string but not too string...
Aqua Velva, great AS, just a hint of menthol but a a great cooling effect.
Edit:
Oh, Stirling MITA - Awesome, would buy more if P&P was so outrageous...
