I agree with those ^^^^ guys.
I am currently using the TSB spring pack with the AAL and I like it quite a bit. It is a little harsh with no load but with the shell and a little load to a lot of load it works well. I also have paired the springs with OME shocks and they seem to be well matched. The AAL is fairly inexpensive and easy to try before you go to full leaf packs.

If you plan for every contingency, itís an activity not an adventure.
