Kalk or Two part?

How big of tank are we talking? If its a large tank i would suggest a CA reactor as this will keep your Ca and Alk at proper levels as well as keep them stable. But, if its a smaller system I think if you use the 2 part correctly you shouldn't need to drip kalk at all.

 

I would use kalk on a regular basis, and use the 2 part to adjust levels where you want them. If you're like me and you slack on your kalk dripping a couple days, your Ca & alk will drop. Kalk is good to maintain levels but not raising them back up. So this is where the 2 part comes in handy.

 

I should also mention, you can just dose the 2 part, but it's kinda a pain in the butt and gets expensive.

 

I don't like to point anyone back to RC but there is still good contributors with plenty of insight.  JDieck posted comparitive cost in a 24, 55, 120 and a 225 gallon system.  Depending on your daily alkalinity consumption, you can determine which is the most cost-effective solution for you.
Personally I got rid of my calcium reactor and I will be going back to topping off with limewater and dosing two-part.  I feel it's much safer because it will be harder to crash a system vs the latter.  I have also considered the balling light method but will try the limewater with two-part before giving that a try.

what is the "balling light method"?

 

You might have missed the hyperlink in my response.  Here's the thread I was referring to.
