That's a tough one. I was going to say Tippet would be the one to weigh in on the Carbon but I see he already has.
Had the opportunity to pick up a Carbon from John this summer, it was one of the first ones he did just playing around with it to see how it would turn out. I think it was the same bow that Chuck from Two Tracks sold this summer, 64" in the same weight. I have not seen one of Johns Carbons that wasn't film dipped, not saying they are all dipped but the few that are out there that I've seen pics of are dipped. One of the draws to Johns bows, besides the fact they are superb shooters, is they are so darn pretty.
Had a Griffin and a Shrew Little Favorite with the Bow Bolt and that takedown system worked flawlessly. Unless you plan on doing alot of flying/traveling the takedown option is nothing more than added cost. If I can't drive to where I hunt I ain't going, not a fan of flying but that's just me. With the Bow Bolt you can't tell the difference between a one and two piece bow. John will only do a Bow Bolt with a Phenolic "I" beam.
I have a 30" draw and shoot the 60" bows in lighter weights well but the 64"s are more comfortable. 64" Griffins are hard to find, John will tell you the 60"s are his bread and butter.
Don't mean to muddy the water but my favorite bow of Johns is the Fiftyniner. I hope I didn't make your decision harder.
The pic's are all 60" bows, the bow on the left is a Bow Bolt.
