Longest wait I had was about six months for my Caribow Peregrine. I just putted it out of my head, and didn't have any problems with that.
Things got difficult when Abe told me the bow was almost ready and would ship within a few weeks. Then I got nervous and got that itch. Those last weeks were very hard and they seemed to last like ages.
Further, I was lucky being able to buy second hand like new bows exactly in my drawweight, like a Whippenstick Phoenix and a RER Vital. Being able to test drive them, no waiting time and they only differ 0.5 lbs in draw weight. What are the chances on that???
