I am going to buy a vibrator for ICF's and am looking for some imput. I am looking at Oztec 1.2 OZ. What size head is best. Oztec makes a 3/4 inch mild vibration head, a regular 3/4 inch head and a 1 inch head. Any recomendations?

The smallest Oztec I use is a 1.8 oz. I would recommend a 1.25 " head but a 1" will work if you have a tight rebar schedule. Any questions please feel free to call.
