If someone decides because of that to not get a Zipper then they are missing out on a top tier bow over something silly.
What someone does with a bow after they get it- IE swapping limbs with other bows, or as Chad says buying a stock bow and taking what you can get from the table for limbs in a custom one at a time situation, is really beyond Bob or Bill's control.
All they can do is OFFER to fix it - I've ordered and seen about 15 of these personally over the last 17 years and every ORDERED custom Zipper has been PERFECT in every way..glue lines, fit and finish, and wood quality. If you are considering a Zipper the NON ISSUE issue mentioned in this thread should not dissuade you from buying one.
I am not endorsed by Zipper, I am not paid by Zipper, I get no special favors from Zipper- I've just used my 1989 Zipper to kill a ton of animals and would trust the bow with my life against dangerous game if need be, before ANY bow I have ever shot..because it gets the job done in every way possible, while looking great as well.
And Bob, and now Bill, like a lot of other folks in this business, are a class act that stand behind what they do 100%
