Hello All! I have been lurking for 2 or so years and this is my first post. Love the site, the knowledge here is awesome! I've been playing for about 2.5 years. I have been playing drums for most of my life. I'm in my early 40's. Anyway....I'm torn between the Mono Vertigo and the Bass Sleeve. This bag would be mostly for going to lessons and sometimes to a rehearsal space. Is the Vertigo much bigger than the Sleeve? I've searched the forums and can't tell how much bigger it is. Is it overkill for my purposes? I don't want to buy the Sleeve just to have the buy the Vertigo later. Thanks, in advance, for the help.
