So, I know it's a tad early but we're looking for wedding bands already. Mine is the easy part, but we are having trouble with is deciding whether to do his in titanium or tungsten. I've priced both and titanium seems to be cheaper at most places, but I hear tungsten is more durable. What are your experiences with this?? Is one better than they other? Is Tungsten really not able to be re-sized because Tungstenworld.com had a lifetime sizing option. Please help!! lol
