On the silver contacts. Given the amount of room we have in there, and the fact that the LP brass nut that comes with it is 3/32" thick; when setting up the silver contact, one should be shooting for it barely protruding from the brass nut. I'm torn between sending the biggest chunk of silver I can / that should fit in the post of the aluminum post VS cutting it shorter so that it will always fit for everyone without taking a little nip off the back end. I figure the longer the silver screw, the more years of use it will provide. Now and again, one of y'all might need nip, file, sand a tidbit off the backside on initial setup; but almost never I hope.
X-puppy sent me some batteries to try out; so I know what all is going on out there. I agree with his take completely.
Both the VTC5 and the LG last substantially longer than the Samsung 20R; but the belly of the curve for the VTC5 is a bit weaker than the Samsung. The LG is solid. Pro'ly the best for punch and longevity combined. Sounds like the new Samsung 25R that X-puppy's trying are on par with the LGs? I think it also comes down to what a person needs too, tho. I don't need a battery to last more than a full day, so I don't need to pay for that luxury. I'll be happy to ride out the 6 Samsung 20R I have for as long as they're serviceable.
