I have both. Actually my son has the Elites and I have 3 sets of elite plus. I really cannot give a mathematical deciphering of differences, but they are both good limbs. I think the plus might be a bit smoother at the end of the draw cycle. The difference between my Ult Pro's and Elite plus are 2-3 fps....
