There are not lines on the 04 cam 1/2 BUT there are performance holes.You should see a hole directly underneath the cables on each cam.
The specs in the Hoyt catalog are for refernce only.All setups and cams will vary slightly.You will need to call Hoyt to see exactly what your cam and limb combo should actually measure.
Why not go ahead and give the Hoyt strings a try.They are getting better.I got mine shooting today and I noticed it settling once after about 10 shots and it seems to be settling in quite nice right now.Only time will tell but it does seem to be doing pretty good so far.Don't get me wrong,if they don't settle in pretty quick,the strings will be gone but for now,I am giving them a shot.(pun intended)
