Originally I wanted a one piece LB, I got a real good deal on a 3 pc. built by the same bowyer and at first thought it was a bit heavy. I am glad for the extra weight as it does seem to steady the the bow arm and help under windy conditions.
I also ended up going on a Texas hunt and had to fly with the bow, it makes it much easier to travel with than a one piece. You should know one thing though about traveling with a take down bow, they don't have to allow you to put it in your carry on bag, they said to me that the riser could be used as a club, so I had to put it with the check in luggage, this was after I had called to see if I could put it in my carry on bag because the arrows were in the check in bag.
It's still a lot easier to travel with even with the car.
I would suggest you get a take down first, and then down the road get your one piece. If your not going to travel do it in reverse.
Hope this helps.
