I used a Herbie's mat with the stock aluminum platter on my Pro-Ject 1Xpression with great results. I upgraded the platter to Pro-Ject's acrylic platter. The Herbie's mat over damped everything; they sucked together. The original felt mat that came with the Xpression sounded a bit better. No mat worked far better.
Like you, it didn't occur to me to skip the mat at first. It wasn't until I saw a picture of a turntable with acrylic platter and no mat playing an LP that I considered it.
