RE: Could someone explain the Cam & half?
"Flex-modulus" is measured by machine and the limb thus given a deflection rating, and it is true that nock travel is dependent upon consistency of each bow from bow to bow. Having said that, it is also true that when you take matched pairs of limbs that are being cut side-by-side every 2.25" from the same panel, that the deflection values will remain extremely consistent. It is only when you get into high-volume limb building through "convnetional" means and they are spit out into a bin and then painted and THEN valued that you tend to get the variations you are describing Jeff. Some companies are far better at the limb building/matching then others, I know some companies that could really care less about this issue, but I also know others who are very aware that the limb itself is one of the most critical components of any bow, and matched sets are a must for best consistency, as is consistently straight and level nock travel.
Not only does exacting limb tolerances help to keep things in synch and the nock travel consistent from one bow to the next, but it keeps the dynamic balance of the bows where it should be also, thus making them much more forgiving.
Oldguy--
Yes, I truly beleive a hybrid is better than any other cam option for not only novice archers, but for anyone. As stated, IMHO it is the next step forward. Many techs have believed this for some time now, including Norb Mullaney. I was a twin cam fan for years, but have come to realize the benefits of the hybrid system through my testing.
JoePA--
Larry is correct in his methodology---the only twins that retain straight and level nock travel comparable to hybrids are the ones with a slightly larger radius cam on top, and to my knowledge only LLoyd built them. The other twins have straight travel, but not level. Solos, are, well, solos, and only a few have relatively straight and level travel, but limbtip travel remains inconsistent on many of them.
I have shot my best groups ever at distance with the Omega (CPS-style) hybrid. And, I do not shoot like I used to-- I put in about 1/8 the time I used to practicing. I have a pretty good handle on what works well and what does not, having been around "awhile". As stated it took me awhile to come around on these hybrids, but they are, in a word, fantastic. Follow the directions and set things correctly on the timing marks, shoot your string and cables in, check it to be sure nothing moved, and enjoy your bow. Pinwheel 12
