I have a handful of the 64s and 26s, but I will probably use most of them for trades except the 64 naturals. Those will definitely get smoked!
and yeah, the msrp on the Opus aren't too bad, but whenever I see them for sale they are marked up into silly territory. My neighborhood B&M has a box that look to be about 5X38s and they are selling for $25 each. lol
still, if price is not a factor, my vote goes for the Opus.
