I have owned 3 bongs and and innumerable amount of other pieces in my life, and with a few exceptions all have been of different styles and sizes. That is something that I stress before I even consider buying a new piece. It needs to provide new functionality. If you are going to get basically the same setup you have now, just a bit taller, why even bother? I think that if you are going to go through the trouble and expense of getting a new bong, try something you haven't had before. Maybe a Roor, maybe a lot taller one, maybe a really heady, decorative one. And speaking from experience, once you get more than one piece that provide identical functionality, you will pick a favorite one and the others will just collect dust. This is just my opinion though.
