Zcoin profits are good, but from what I can tell it's pretty comparable to other coins (like LBC when I looked earlier today) on that dude's rig. 

Basically it's just better to mine whatever is most profitable after expenses rather than hunt around for pools and whine on forums that you can't mine this one solitary algo. He even said he would rather mine zcoin with the pool stealing 50% (supposedly) than mine something else.

That's not even including the fact that there is so much uncertainty about the hashrates for lyra2re2/lyra2z.  I will concede that mining with way less noise and power on that Lyra2z algo is pretty nice.
