A question on 4# foam:
I'm doing an order from foamforyou.com, and I was considering buying a sheet of the 1/2" 4# MC they have there. Right now I'm using the Gold's Gym puzzle mats for my boxes (I route my fries), and it comes out to ~1.07/sqft, whereas the FFY 4# comes out to ~2X that (assuming $15 shipping cost with my other foam).
On my two reds (one 56" and one 51") both boxes are made on the Big Lots puzzle mat, and the tips are starting to fold over. I mean to say that the box tips have gone soft as well, and are destabilizing (both are stabbing, and I stab quite frequently).
So, my questions are these:
1) Is the tip going soft in ~6 months typical of all puzzle mat boxes?
2) Will I still see that in the FFY 4# as well?
3) Would those of you that have experience with the FFY 4# recommend it? Could you attest to its superior longevity?
Thanks for patiently reading my wall of text, and thank you in advance for your advice/assistance.
P.S. I've also noticed that the side walls of the puzzle mat tend to be quite a bit harder than the 4# fries I've handled (I believe Silly and Cas got them from Alric). Is this indicative of some flaw in the foam, or a sign of poor quality foam?
