Eco Sol Max or Eco Sol Max 2?

Good morning all,

We have taken the plunge and bought a new BN20 with the CMMYK ink setup. It is coming in a few days with the original Eco Sol Max inks but i'd just like to get a last minute bit of advice if this is the best option or whether I should go for the Eco Sol Max 2 instead. Reading a lot of info floating about on the net I have opted to rule out Max3. I have one day left to make this decision so any quick constructive advice would be most welcome.

Cheers all...
