Hickory Smoke Salt

I usually use seasoning salt in my rubs. But I have been wanting to try some Hickory Smoke Salt in my rub. Has anyone tried the Hickory Smoke Salt? Should I take the seasoning salt out and replace it with the Hickory Smoke Salt? Or would it be better to go 1/2 seasoning salt and 1/2 Hickory Smoke Salt?

I use Watkins Hickory Smoke Salt in all my rubs. As Spice sez it is quite salty so watch the total salt content.
I've quit using seasoned salt as a rub ingredient, most of the components of seasoned salt (salt, sugar, paprika, onion and garlic powders) are spices I use in the rub anyway. If you use seasoned salt you have no control over the amounts of each as they'll vary brand to brand and to a lesser extent batch to batch with the same brand, so I just add those things myself.
