I wanted to get my first bong and I wanted a bong with a slide bowl but I really liked this bong but I don't think it has a slide bowl. It says it has a carb hole with carb stoppers but the bong looks nice. Should I get it ? http://www.grasscity.com/us_en/black-leaf-worked-dome-percolator-ice-bong-yellow-blue.html#.VCddb4r3bCS Slide bowl*
