From my experience I've concluded that they all shoot equally well when timed and tuned properly with a correctly spined arrow. Each is different in the ease of getting to that point. I've always found twins to be more critical of timing. It took longer to get them timed and was more critical that they stay there. An out of time twin shoots a broadhead terribly. In the past, they were louder, had more vibration and were best in the hands of a knowledgable archer. Today, most of these are no longer issues, but syncronization is still critical and those shooting stock strings will probably still experience problems.

Singles are easier to get tuned and syncronization is not an issue. In the past, they had issues with string creep and stretch. An archer who knew the basics, could easily check this and keep the bow tuned. It was simply a matter of adding twists to the string to maintain proper length and checking the position of the string nock periodically. With a good string, this is no longer an issue. My last string only stretched 1/16" with 6 months of shooting. Some singles do shoot broadheads better then others. This may be an issue with nock travel on those particular manufacturer's cams.

On hybrids, there are timing marks, so timing is necessary, though not nearly as critical as on a twin. Singles are easier to time, in my opinion. Hybrids have fewer string issues then the others, because they're shorter and less critical of problems with stretch or creep. From what I read, nock travel is not an issue, but then again nock travel does not appear to be much of an issue on a timed twin, or most late model singles. However, I would have to rate hybrids as tops in nock travel. The real question: Just how important is nock travel? I have a feeling it's much more important when shooting broadheads, then when shooting field tips.

In my opinion, rating one better then the other, comes down to the cams inherent forgiveness and the ease of getting it timed and tuned. They can all be made to shoot equally well. That's been proven. Some will simply take a bit more work or more expertise to get it to that level and to keep it there. I would rate the hybrids as slightly ahead of singles in this department. Twins bring up the rear, in my opinion. They shoot great when you get everything perfect, but the average bowhunter doesn't have a clue how to accomplish or maintain this. It only takes a slight movement on one cable to throw the cams out of sync. causing the bow to shoot a broadhead terribly. An archer who knows little about timing and tuning, is better off with a hybrid in my opinion. A knowledgable archer will have any of them shooting fine, and so will a good bow shop.
