Speakers for JCM 2000 TSL 602

I'm looking to upgrade the speakers in my amp.

I like a high gain tone but also a Nashville clean. The amp is 60 watts RMS and Two speakers wired in series for 16ohms.

I like what I'm hearing from the Invader so far. Would two of those be good? Would I be better off having an Invader and a Veteran 30?

 

Thanks.
