ya ive made bongs with both carb and slides and personally i like slides better. now a carb is easier to use but the carb just seems so much cooler and it lets more air in to clear the bong. and with the bowl, just be careful wen you lite your bud because one time i didnt realize that the heat from the bowl was melting the plastic pen tube and my lungs hurt afterward and i threw up. so watch out for that
