I seriously doubt if there is much advantage for people who are maxed out on camshaft technology on their hydraulic lifters. The ramp profiles on those cams are taking assuming that after .015" lifter rise, the lifters are solid anyway. You might be able to speed up the first 6-10 degrees of the ramp a bit with a solid lifter and drop it a bit quicker. One thing for sure, there will be a lot of camshafts sold next year!
