Rock,
I'm not trying to be a jerk, but I truly don't see the Thunderhead Razors test. Are you shooting the NAP HellRazor?
I'm actually in total agreement about what might happen with these Mechanicals. But I won't know until I try. No one else had the Forum even had a review on them or anything about penetration. Thought I would be the one to give them a try and report.
