I strongly suggest you do a search on solo vs twin, and maybe another on nock travel. You will get some good feedback on stuff that has already been discussed in detail.

Twins are better than solos in practically every technical area, and 20 yds is no true measure of accuracy to be honest--try the same at 80 yds and see what happens between the two. If I could learn how to move posts around on this messageboard I' d paste the reasoning why here for you. They have now upgraded conventional solos to the new wave of hybrids, already up to " cam .5" , etc., eventually they will re-invent the twin cam... In 2004 virtually every manufacturer will be offering a hybrid of some sort, and conventional solocams are destined for extinction now matter how much Matt McPhereson crys foul. Hybrids are simply that much better. Especially ones that DO offer straight and level travel. (cam.5 does not, but probably will for 2004)

This is what the crystal ball says. Technology moves forward. JMHO Pinwheel 12
