bowfanatic, if i remember right the old command cam was only availiable in 75% let off and the command cam + is availiable in 75% or 65% let off. yes there is a little harder wall on the "+" but it doesn't feel as solid as some one cams i have shot. i like the command cam + for the smooth draw and the adjustablity to it. i have owned 3 bows with the command cams and once the strings were broke in and the cams rotation retuned they never went out of time again and i mean never..... i was very sad to see the command cam go as i'm sure others as well. i really don't see the need to change the cams the ones you have there already are great. the cams you have came out i believe in 98 or 99 and the plus came out in 02, and they have the same adjustability. good luck.....
