I love reading this thread. Titanium is expensive, but you will not find me out in the woods without my 3.5" titanium call. I love it that much!
My 3" one, wow that thing will really ring your ears. I had a hard time convincing Daryl to let me get that one, but he did. It's all turkey, but there is not a caller out there I've found that is louder than my 3" titanium. It brings a new meaning to loud and proud to me. It's one of the few calls the wife has honestly laid down the hammer and said no way I can play it in the house.
I am not having the issues of the surface slicking up at all. Treat it just like copper and it was used a lot last spring. Took it out just now and didn't even touch it and away she went singing again
I do have a special striker for it though. Just like I do for my copper pot.
Now I'm not real scientific on the sounds, but I think some of these are on to it. Not sure there is a lot of difference between copper and aluminum though... I think just saying I have a titanium call is cool
