From the outside looking in, I also get the sense leaks aren’t so much an issue these days. I say that based on chatter across several forums and particularly over on AGN. Besides, we know the kinda guy you are. If there’s a leak, you’ll get it sorted out in short order! The most common thing I see is questions about regulator creep. It has been difficult for me to get a read on what percentage of it is a real problem versus simply not having the hammer spring tension set to the velocity knee, but no doubt it’s less of a problem that you might at first think based on the amount of discussion devoted to the subject. For example, on quite a few occasions I’ve advised people seeing 3 bar of rise or 5 bar of rise. That’s well under 100psi, whose effect will evaporate when tuned correctly.
