I fully recomend the bayonets as deep as you dare go. Larger opening, can do a further spacing if desired, and the width of the bayonet is the same as that of the needle tine. Larger space stays open longer, and disrupts the same as the needle. They have worn better for me, won't break off when weak in your pushups, and as long as you are doing the process, why not have an open hole longer. I like to roll following (or mow if no rollers), and topdress not far after either just in case you do have any denting.
I've found the key is to acquire a longer tine (I use 5.5's in a procore 648), and not bury it to the flare at the top. I got in about 4" for the front nine, and then to 5 on the back to accomodate for the tip wear that does and will occur. More often than not though, they will make an entire 19 for me without wearing the first go through. I don't know what type of mount your machine has, but we stagger on quad block front to back to be able to increase our ground speed, getting more holes more quickly in the surface of the green.
