I agree that, at least in theory, tangential arms are superior. Now, if they could just make one at the same price as a simple pivoted arm...I don't know what kind of computer system you have, but with any windows compatible internet software I've seen, posting links is easy. Just right click on the address in the address bar near the top of the page when at the page you want to link to and then click on "copy" in the tool window that shows up. Next, when you are posting on the forum, right click and then click on "paste".
I've no idea how non-windows compatible software works.
Please don't waste forum space re-printing an entire article just for me.
