Question: I would like to say in German,

> 
> I would love to talk sometime.
> 
> 
> 

So far I have this,

> 
> Ich würde gerne mal reden.
> 
> 
> 

Is *reden* the right verb here? How would you say it?

Answer: 
Although the given answer is correct, I would like to distinguish cases more:

> 
> Ich würde gerne mal reden.
> 
> 
> 

This sounds like you would like to talk, no matter with who, when, or what. You could be very shy and desire to step up and talk sometimes.

> 
> Ich würde gerne (mal) mit dir reden.
> 
> 
> 

This answer was given in a comment. It is correct, but has a special connotation. It somehow implies that there is a specific topic or at least a specific reason for your conversation.

> 
> Ich würde mich gerne mal mit dir unterhalten.
> 
> 
> 

For the general case this is the best answer. It implies that you would like to have a chat with the other person on another occasion. Depending on the context this might or might not have different connotations, for example like the answer before, but in general it is just a friendly thing to say.
Irgendwann würde ich (sehr) gerne mal mit Dir reden.
