Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
I can tell you that there is no answer. Do a search for salt on here and you'll get a plethora of "This is the best salt" followed by "I hated it for X, Y and Z reasons". What you'll find is that different salts work for different people and if you're content with the salt you're using now then there's no need to switch. I've switched salts too many times to be proud of over the last year and in retrospect could have just stayed with the original for all it has proven!
