I have many bows including one, two and three piece models. I like all of them. The one piece is the simplest and lightest, but it is not the one to use for travel. The three piece is the most versatile and stable (due to its weight) and also packs into the shortest space, but it is heavier to carry around all day. The two piece is light and feels pretty much like a one piece, and it breaks down into a slim package that is about the same length as your arrows. I suggest either a two or three piece bow if you ever plan to travel to hunt for some of the reasons stated by Rick P along with other considerations. For quick assembly/disassembly nothing is faster than a two piece takedown. I can take apart a Bow Bolt in two seconds and put it back together in five seconds. Some of the other connections require about the same time. An ILF bow is pretty fast because you don't have to screw in the bolts on most of them, just slip the limbs in and string the bow. The limb bolts on most three piece bows take some time to put together, especially if you use the standard bolts that require an allen wrench. I would much rather be using a two piece if rapid disassembly and reassembly was required, plus you never have to search for a tool. If I were disassembling and reassembling my bow while actually out hunting, I would use the bolts that can be tightened and loosened by hand.
