I love it! Titaninum is a really strong metal, so its less likely to bend/break/scratch. My husband's band is titanium which is great because he works with his hands and was likely to break it :)
From what I've helped friends build, you can use a stand alone grill, but generally you get better results either with expanded metal in a frame over a stone/brick firebox, or using steel/stainless round stock welded into a frame over the same firebo...
Titanium is stronger. Platinum can be used to make jewelry, so it can be formed and pounded into shapes. Titanium is much harder to machine and form into objects. .
