Thank you for the reference, LatigoAmigo. Maverick sells second runs of CXL, which, depending on the project may be a better buy than Tannery Row's. I've been planning to get some from Maverick, just need to call them up to get more details.
Just looked at some 8-9 oz black CXL sides (18 sq ft average) at The Tannery Row.
$260/side
Most economical shipping cost: $94 (ouch!) for up to 3 sides to ship to southern California.
No tax though.
