There are 4ea 7/8 inch holes on the Weber lid. I won't stake my life on this but I believe 4ea 7/8" holes are a larger area than 8ea 1/2" holes.
Norco said 8ea 1/2" holes are plenty and I imagine he would know.
I've seen people claim that the Weber style vent creates a hot spot. If I find this is true I may drill 8ea 1/2" holes in my Weber lid and leave the vent closed.
Before I drill up my Weber lid I'm experimenting with mixing up the heat flow in mine. I'm putting a grate below, about 10" below my cooking grate. On this grate I'm putting a 10" aluminum pie pan and will put some 1/4" holes in it. I hope to deflect the straight up heat travel into going around that pie pan. Maybe I can get the 50 to 70 degree heat difference between the side wall and the center to even out a bit. I imagine I'll have to tinker with it for a while to find the optimum.
