I don't know who is right here on the bigger issue.

"Yes, I firmly believe the twins, (when tuned correctly) are more accurate in the average archers' hands"

We could probably also argue about what constitutes the average. But if, for instance, we mean the statistical average archer, then in general he/she isn't even active in target shooting, and isn't interested in spending a lot of time tuning either. That is why the solo cam is popular, because it promised less tuning (true or false isn't my point). To say a dual would be better if people would just do the thing the marketplace clearly shows they are unwilling to do might be a winning argument in some parallel universe...

I'll now turn this argument back to those who know what they are talking about.
