I have brewed a couple of all grain batches with my friends cooler style tuns. I am setup to brew ten gallon batches so I am looking for a tun that's large enough to accommodate but not leave superfluous head space. I also tend to brew big beers. My last 5 gallon batch called for 22 lbs. of grain. Right now I am thinking of buying this one...

Too big? Too small?

Also, I am going to be building a manifold. I have read many threads debating the benefits of bazooka tube vs. manifold. I have decided to go manifold. I'm not sure on CPVC or Copper? Benefits outside of cost?

Any help is greatly appreciated!

I use a 10 gallon bev cooler and can accommodate up to 23lbs of grain. I use a copper manifold and it works great. My concern with CPVC is it is not food grade material and may cause issues with the mash, I could be wrong, just my .02

Do you think that a 30 gallon would leave too much headspace?

Depending on the size of the grain bill if there is.a lot of empty space you may have a harder time maintaining temps during the mash.

I have a 5 gallon and a 10 gallon round cooler with copper manifolds. IMO copper is the way to go. No issues with copper at all. Just put your drain holes on the bottom of manifold. I learned that the hard way.

I'd splurge on the 1/2" stainless valves and bulkheads like these http://www.bargainfittings.com/index...tegory&path=47.

I used the Lowe's brand brass fittings originally, but switched to these. The cost is about the same once you factor in all the pieces and parts you need to make the Lowe's stuff fit properly, especially the stainless washers.

Bobby M has a handy chart for sizing cooler tuns http://www.homebrewtalk.com/f11/how-...-needs-123585/

you may also want to look at Bobby M's bulkhead design also. I did mine this way and have never had even a single drop leak.

I use CPVC. Easy to cut and drill and cheaper than copper. I don't worry about food grade since it's rated for potable hot water.

I have their 70Q version and regularly have ample head space. Here is a picture of 23 lbs of grain at 1.25Q/lb ratio. I could probably fit another 20lb if needed. I hope this will provide some perspective

I went ahead with the 70qt cooler. Now I just need to figure out the best manifold design...

Some good info at john Palmers book site. I followed his specs and it works great. I did cut slits and drill holes between slits.
