Randakks stuff is known to be top notch. Like was said earlier, the only argument for or against spin on filters is whether it is really worth it. Your oil is getting filtered regardless, so go with whichever makes you happy.
(THAT'S FROM THE LAST "DEBATE" ON SPIN ON OIL FILTERS)
But... there are no negatives! At least half this board is about changing and or modifying old bikes. This is just one more way that can be and is done. It's really funny yeah, some guy is going to reach down between two very hot pipes and grab a hot oil filter and twist it off by hand? If someone is that heck bent n damaging a bike they will do it regardless of spin on or no spin on. Most of the posted "negatives" are made up stuff flying saucers er, I mean rocks and vandals or moto terrorists, I guess there's been a rash of new bikes being vandalized and hit by flying rocks because most newer bikes (and cars) have spin on filters. Give it up, too funny.
