Hey Rick,
KK here. I don't have a lead on the OPST lines but if you ever want to order from them directly and ship to Point Roberts, I use a shipping service there and could pick it up and mail it to you. I go down there at least once a month. Let me know.
I have a number of the commando heads and they are awesome. I use a 200gr on a sage one 10' 5wt, a 250 on the one 690, 275 on the one 796 and the one 5116, the 325 on the VXP 896 and the VXP 6129, and the 375 on the method 7126 and the 8119. The 375 on the method was the real eye opener, I usually cast a 530 Airflo Skagit compact on that! They are great lines for single handers in tight quarters; haven't tried them on the beach yet but I am curious to see how they perform in the salt.
Hope you're well and that the fishing has been good out your way.
KK
