Hi, I currently own the Lowepro Computrekker Plus AW. I love this bag, but it is quite large. Lowepro says it's airport carry on legal, but I am a little worried. I really don't need to carry that much gear on this trip. I'd like to take: 40D with grip 70-200 F2.8 L IS 24-104L 50mm 1.4 17-55 F2.8 IS 580 EXII Flash. 15 inch laptop and accessories. I am looking for suggestions for a good bag for travel thats not too big, but still roomy enough for that gear list. Maybe the computrekker AW? Also, has anyone traveled with the computrekker plus? Did it fit on the plane well? Overhead?
