If you have one slide, you are not into slide or just like to wear your underwear for a week at a time. Jazztele, you have a nice touch, nice enough for you to recognise differnt feel & sound from differnt slides. I like weight, so heavy is fine. THe glass needs to be thick as I feel it better sustains. But it is best to have a brass slide, a stainless steel slide, a couple of differnt glass slides. I even have a craftsman Lowell George sized one. Porcelin seems to break easy.
