Jay may analysis is this:

the only way to prevent valve float on a higher lift /duration cam, is reduce ramp speed and harmonics. Harmonics are less of the issue here...that has more to do with stresses placed on the rockerarms and lifters. valve float is more of a function of ramp speed of the cam. If you have a 2 cams that are opening the valve for a duration of 264-266 degrees (essentially the same) the one with the slower ramp speed to control valve float is going to open the valve slower. the degree of the cam doesnt measue how long the cam is at max lift...only how long it is open. the slower ramp cam will spend more time at 0-90% open and less time at 100% open. Maximum breathing occurs at 100% open not 0-90%. I'll take the HKS for this reason...faster ramps...but more time at 100% open.

That and i just dont like JWT. Their ECU programs have proven themselves to be garbage tiome and time again. If they cant program ECU's then i don't see how they can possibly design cams...programming ECU's is ALOT easier than designing cams.
