We recently purchased new wrestling mats and wall pads. I researched all the companies and ultimately decided to go with Resilite. Even though the expense was higher than the light weight mats, the feedback we received from a number of coaches and facilities is that the Resilite wrestling surfaces are more "forgiving" than the lightweight foam mats when it comes to repeated falls and drilling. The best explanation I received was "there is a reason why every D1 wrestling room has Resilite mats"
We did use AK Athletic for our wall pads. They were the lowest priced option we could find for wainscot type wall pads. We are happy with that choice as well.
All being said, if I needed a mat that was going to be moved a lot due to space or duals, I would have bought a lightweight mat, but for a permanent room, we could not have been happier. Matt at Resilite took care of our order and being a family wrestling based business, I am glad I was able to give him our business.
I do recommend talking to coaches that have both options. To us, the choice was worth the additional expense.
