Default RE: Could someone explain the Cam & half?

Jeff brought up many good points on this one that cannot be overlooked--

1) That there are two different types of "hybrid" out there-- Hoyt's is more like a true twin cam with respect to their eliptical cable track which, depending upon drawlength, may or may not offer level nock travel because of it. Twins have straight travel, but not level, so the cam.5 is a step forward if you hit the correct drawlength.

2) The CPS/Merlin Omega type systems have a perfectly round cable track and can offer very. very straight and level nock travel at all drawlengths---this allows shooters to use a wider variety of arrow selections, and allows for easier tuning across the board. Remember that ALL bows require tuning---twins, solos, hybrids, all of them. Solocams for instance are very finicky of arrow spine and normally do NOT allow straight and level nock travel at all drawlengths, and especially those that offer drawlength adjustments over a wide range on the cam. I have found the hybrids to be the best of the cam selections simply because the CPS/Omega type allow for "set it and forget it" tuning and some brands even come with complete instructions on how to do this for best performance. They offer the best attributes of BOTH twins and solos, and take most fallicies of the two out of the equation. They're not susceptable to nock point movement like solos are because both ends are slaved, and they are not as finicky as a pure twin so you need to get it down to the nearest 1/2 twist to find the "sweet-spot" for great flight and groups.

3)Another great point was limbtip travel and it's association to different cam designs---all bows should have both limbs firing at the same time and a geometry capable of allowing this for best performance and consistency. Solocams are notorious for NOT allowing this due to different sized and radiused cams and idlers---throw your favorite bow in a crankboard, run it out to full draw, pencil around the limbs, back it down halfway, pencil again, and measure between the marks---are they the same? If not, you may be experiencing poor accuracy due to the "kick" of one limb firing completely before the other...not good as a rule. Some shooters alter their bows' geometeries to help with holding and allow the limbs to fire one before another---this IMHO is also detrimental to proper accuracy and performance, and one should find a bow that holds good and fires with even limbtip travel for best consistency and forgiveness.

Many many manufacturers now have a version of the hybrid, and it is without question the next step forward in the evolution of compound cam design. All who do not offer one soon will,(well, except maybe Mathews) and we will soon see new and improved variations of this design in the coming months and years, simply because there is much room to move forward technically with this system as opposed to others. Good shooting, Pinwheel 12
