Just finished venting greens with bayonets yesterday. I use JRM tines that fit in the quad block (10 tine holders) and I try to space them evenly front and back. Typically I use the alternating 3 holes in the back and the middle two in the front. In the 3 spacing, it gives a pretty good 1.75" or so pattern, and is very fast. Roll behind.
The JRM tines are 1/8th inch wide and 5/8" deep and approximatly 5.5" long. We bury them into the surface as deep as we can go. Very minimal disruption, and I try to lightly topdress soon after the process. Invaluable for preventing LDS and encourages good root formation.
