I've checked the archives on this, but I'm finding so many variations in the
price and thickness of this product I'd like to find out what thickness and
brand those have you who have done this used.

For those who don't know about this mod see:

I've seen it up to .030" inches thick for about $60, but that seems like it
would be better for the bottom track.

My philosophy is usually the bigger the better, including debt.

Thanks!
