Re: MD 1 vs Five Mega P3 ...any thoughts?
I have both - unfortunately, they are both packed away at the moment, so no pictures. Some observations:
1. The MD1 has no native anti-roll feature. The 3P, using a SF bezel, does.
2. The hi/low ring was hit or miss for me. I heard that Gene is amendable to swapping out resistors on the hi/low rings; that option might work better for you.
3. The MD1 was a bear to get apart; if you intend to swap out drop-ins regularly, the 3P is easier to tear down.
4. The 3P can rock the SF "combat rings" if you need to improve gripping and retention elements.
5. The MD1 comes with a forward clicky/tailstand feature native. The 3P (probably) has a twisty tailcap, although can certainly be upgraded to a McClicky - no tailstand functionality.
