Kraken really is the bomb. That's been my go to for a long time now. Was just drinking that over the weekend actually. Never tried it straight up tho, but it really is smooth so I imagine it would be nice.
Yeah, bad tequila needs salt and limes to cover the aftertaste. Good tequila should be sipped and enjoyed for its pleasurable flavor. Notice, the tequilas they have are almost all crap. Cuervo, especially, is drain cleaner, IMO.
