@element77, I would suggest that when you're mounting your MM coil, be really careful about unscrewing the post screws to the point where they come off. They are HORRIBLE to get back on if they've come all the way off.
Also, they are tiny and would be impossible to find if they happened to drop to the floor....my floor, anyway (carpet!!) Not to mention they cost $6 apiece to replace them....if you can even find them in stock. Just be careful.
I agree that maybe another slit going perpendicular to the original one might be nice, but at least the one that's there is wide enough I can use a bigger screwdriver in it. My tiny little Dollar Store specials or my tiny little jeweler's tools won't work. Had to break out my "real" screwdriver...
After you mount your coil, make sure you check ohms with the cap on. It's a tight little chamber with not much headroom.
