I have the 100 and 200, and have not used Kata. I hate the sling packs. The 200 barely holds my 1Dmk2, 70-200 2.8 and 17-40. Wear and tear wise, the 200 is showing signs of loose stiching, the cover isn' all that great either. The slings place more pressure on one shoulder and this bears down over time.


I personally swear by Think Tanks Skin system. The most comfortable system I have ever used. The only time I ever use a backpack is when transporting lenses on an airplane or a train.
