Replacing cam, want suggestions

Haven't talked to them yet. The Lunati cam looks like it fills the gap between the Hughes HER2228 and 2836 as far as lift goes, and has slightly more duration and less LSA (110 vs 114). The hughes lifters look like the way to go now with the lower groove, but I don't don't know if I'll get their cam. I'll ponder it some more, don't totally understand overlap, opening/closing degrees, and LSA, other than smaller LSA lowers torque RPM.
