If you have this bag...is it comfortable? Looks like it may be a bit bulky/uncomfortable? hmm.. Looks nice n' roomy though...Seems like your arm would stick out then hang over it..like it may be too structured/wide or something... Also from the pic at Elux.. http://eluxury.com/browse/product_detail.jhtml?styleid=10517388&SectionID=6000 ..the opening looks like it may be hard to get in and out of.....Do you find that the opening doesn't open wide enough?? Like it's too tight/narrow? Thanks!
