Angled stud backers

How many people use angled stud backers?
How many use plastic backers?

I had some square plastic backers in my old track made by Saber at the time. I'm thinking about putting in angled plastic backers in my next track when the time comes. I run the old Saber ones without any failures,of course I didn't drag race the sled or anything like that either so I'm sure that made a difference.

Anyone using the Accord plastic backers? Are they any good?

I ran plastic backers shortly after they first came out and was not satisfied with the durability. I don't know if that has changed any with the ones of today.
