I think the level of my walkway from Olde Towne out to my beach house might be a good model. It was treetop tall, which should keep you safe in most instances even from spider attacks if you build it the right way.
I am personally crap at the Nether and I *definitely* want glowstone, so on that point I disagree with Bryson.
I'll pitch in for the SSD, RAIDed or not.
I personally feel no need to keep any of my Loch Green structures, but others have made nice things... I figure it's no prob for Brad to move those as well.
I *do* need to eat the cake that Mrs. T made for me before we go though
Edit:
Wanted to add a sentence that didn't begin with the word "I".
