Best Alignment Pad?

I'm not looking for referrals to best buddies products ....

I'm not looking for the most expensive, hence "best".



I'm asking who currently makes the best FF/FC size (100" WB) alignment pad for 15" scales.



My definition of best ....

REPEATABILITY!

Ease of transport

Ease to setup

Cost

Durability (repeatability after bouncing around trailers for years)

Stiffness/flexibility in appropriate places

Proximity to Buffalo, NY :)



Thanks!
