What's the best MJ bag for all year round?

I agree, I use my MP almost everyday because it's not too showy and great to lug around lots of stuff because it's not too heavy... The blake is great too, just a tad heavier.
 
MP if you're looking for a decent size without the weight of the venetia...if you don't mind the weight and the fact that it's not a shoulder bag then venetia will do as well....
