Sorry to some of you but 192 is too many. Also 1/4" penetration is too short. Aside from more weight and rotating mass, they don't hook up near as good with 192 as it would with 96-120. Ever see the guy that lays on a bed of nails? There's so many that none of the penetrate. Same with studs, too many and weight is distributed to the point were they don't penetrate. What's the pont of spending the extra $$ on studs and putting more weight in your track if it does you no good? And don't say that less will cause pullouts... that is only true if it isn't studded right. Not enough penetraion will cause the lugs of the track to bottom out on the ice after the first swipe of the track as it spins on the ice. Again, not worth the $$ and time in studding. If your going to do it, get at least 3/8" min. penetration... I usually run 1/2"-5/8" penetration.
