So a further clarification of the cam issue would still be appreciated - are there really two cam versions (1.5 and 2.0) offered for 2012 Onza 3? I checked a couple other web stores and they did not have the option of selecting the cam, even though they were referring to the 26"-30.5" adjustment range.
Another question about the Nitro cams: I have a brand new Onza 3 (2011 model but without the TRG/SOS). I use 29" draw length setting of the rotating modules. I noticed that after some test shooting (tens of arrows), I can already see some wear on the serving of the cables - they are two tiny white spots where the cables go over the seams between the cams and the rotating draw length modules when drawing/shooting the bow. There does not seem to be anything wrong with the finish of the cams or modules, but as you know, there is a dip between the two.
For those that have been using bows with Nitro cams: have you observed this wear? Has it caused any problems such as cable failure or does it hold well in practise? At least I haven't heard of a cable failure.
