So I just receive my 2lb 1/2 inch cross linked polyethylene foam from foambymail.com and to me it feels like the gray fatigue foam that I get from Harbor Freight that I use as my first layer on my swords. This is my first time ordering foam online instead of going to the store and buying it, so I'm feeling I may have order the wrong poundage. I honestly don't know a lot about the different poundages and what foam is what poundage. I followed the link that was put on the wiki.
what ever help or advice would be appreciated, thank you
