I have always maintained that if it has a moving part it needs to lubed. Metal on metal. When you clean a gun you lubricate it. Some tension rods/lug receivers have finer threads than others. My buddys Pearl masters kit is very sensitive and smooth with tuning whereas my old Yamaha Maple Custom toms had very unforgiving tension rods lube or no lube. My Recording Custom lugs are very standard and tune really easy. Personally, I think all drums need to be tuned and maintained on a regular basis so unless you club your toms like a seal, you shouldn't have back out issues too much. My old Gretsch drums with die-cast hoops stayed in tune no matter where I had them stored, play them, etc. The hoops really make for a clean and concise drum sound if you know how to tune. I usually use wd-40 to clean them, towel off the excess, and then use vaseline or not. The thing about vaseline is that if you do use it you have to make sure to get off all the excess vaseline because when it gets dirt in it it turns black and can ruin clothes or towels just but brushing against it.
