Royal Oak domestic vs. Royal Oak Argentina

I bought a 20 pound bag of Royal Oak lump from GFS (Gordon Food Service). I paid $9.99. It has 'Made in Argentina' on the side of the bag. I think it's better than the domestic Royal Oak that I bought from Wal-Mart. The lump pieces are bigger, and it seems that they burn slower than the domestic. I was wondering if anyone else has noticed this. Comments anyone?

Thanks,

Mel
