Karl Juelg asked for some guidance on his Strauch Brothers player
action [240508 MMD]. The pouches seen in the photos look to be perfect.
The valves, however, in those actions are particularly pesty in most
all regards, with very little room to work.

Send along a few photos of the valves. Is the stack tight?
