I have logo-ed Ultimats in one car and the Heavyweights in two other cars.
My ideal combo: Heavyweights with a logo (which they don't do)
I've had really severe bunching with the Ultimats...I should have sent them back right away but did not. It happened soon after installation, looks like they used too much heat. Mats are very nice otherwise, logo is very sharp, well-done. Durability is very good, slight fraying starting to show around the logo.
The Heavyweights are beautiful carpet and have proven to be some of the most durable floor mats I've owned and show no signs of detioration regardless of what the wife/kids do to them. In fact, they still appear brand new. However, since no logo is offered, they do look sort of "plain". No bunching with these babies!
Lloyds will color-match if you send them a small sample. I'm gonna do that the next time I order.
