I specifically said Flex. NOT the LC adaptor. Here is the link to the Flex North America site:
Welcome to Flex North America, Inc. - Your Heavy-Duty Power Tools Suplier. Find a 4" backing plate there.
Now look at the fourth pic down in this promo thread:
http://www.autogeekonline.net/forum...401-users-have-been-waiting-lake-country.html. See how far the pad is from the base of the polisher? That's what is wrong with adaptors in general. They are add-ons. In this case it looks like they move the pad about 3/4" farther away from polisher base than a native Flex backing plate. That will affect handling.
Do you know of any independent reviews of that LC system? I can only find one and it wasn't that independent. The manufacturer provided a pre-release product to someone.
Do you have that system for your 3401? Share your reaction to it?
