Hi Guys

I have decided to go with the NN5 Stand Alone at this time based upon my budget. I had the following questions:

1. What quick plate do I need if I use an Acratech Ultimate Ballhead?
2. I use the Manfrotto 055CXPRO3 legs that has a spirit level on the base of where the thread mount is for the ballhead. What major advantages does the EZ Leveler II provide?

Thanks in advance,
