When I batch sparge is it that important to use even amounts for both the strike water and the sparge water? If so, should the amount of strike water match the sparge water before or after grain absorption?

Are you saying using the same volume of water to sparge with as you mash with? Normally you'll sparge much much more than you mash with...

Denny Conn says to use two equal sized runnings when batch sparging.

I think he means use 2 equal sized batch sparges, not make the sparge equal your first runnings, but I'm not sure.

Sparge volume will affect efficiency. The more you sparge, the more extract you get in the kettle. I don't care about efficiency as long as it's pretty much consistent, so I typically single batch or no sparge to avoid husky, tannic flavors.

You wont extract tannins if unless you have a crazy ph. Its been said to use more sparge water than your mash.tannins are a result of ph.People are paranoid of tannins

+1 to that. i usually fly-sparge, but when i batch sparge, i do a single batch. i won't do anymore due to temp concerns and adding tannins.

Yes, that means that there will be 3 equal runnings- 1/3 out of the mash/ 1/3 out of the first batch sparge/ 1/3 out of the second batch sparge. That would be the ideal way to reach the boil volume with a batch sparge.

There is no difference, as far as tannins are concerned, between performing one large sparge or dividing it into 2 smaller size sparges.

I also agree with the earlier poster that people seem to be too scared of the tannin monster.

I don't really look too much into making things equal. I just use a 1.25 qt/lb ratio when mashing and figure out how much sparge water I need to hit 6-6.25 gallons from that. It usually comes out to about 4 gallons in the sparge, which I split in half to do two 2 gal batch sparges.
