I know much of this information could be found by reading many posts and such. However I thought it might be interesting to have a specific thread that addressed why you like certain backs that you actually use.
I am hoping this will not become a contentious discussion so maybe we could limit it to your specific experience of why you like what you use. No arguments please. And I know I would be most pleased to hear from the reps from the different companies too. Let's hear what you guys have to say.
Thanks!
