They are about the same as the cams you have on your Z now,just have a longer lobe on top cam for patent purposes.You dont even have to change string and cable lengths.They are built heavier than the Hybrix and have a slightly deeper string groove.No wear problems that I know of.I did change mine over to roller bearings.

String 59 cables 40.5 limbs are 145 Barnsdales.That falls in between the 01 and 1 Martin limbs.(I think) The Barnsdales max out about 63lbs on the Z
