Hi. I was at Nordstroms the other day looking at the MJ Bleeker and I really liked it. Before buying it, I thought I'd ask others their thoughts on four things: 1) Do you find that the pushlock is an annoyance? 2) Does the pushlock scratch very easily? 3) Do you find the bag a tad heavy and hard to carry on the shoulder? 4) Do you think that this is a "classic" style that will endure more than one season? Thanks.
