I was just doing some reading and saw some info about these isky roller lifters... Seems like a great innovation- they have mastered the tech with a bushed roller rather than needles in the bearing...

Probably still not exactly street friendly- but at least you do not need a complete tear down if a lifter fails- these isky lifter might wipe a cam if a lifter fails but you wont have 100s of needle bearings scattered through the sump...
Anyone used them before?
