Well I’m not sure how much help I’d be; my pole is the only one I’ve ever used. Is your pole chrome and the ones in class titanium??? https://www.studioveena.com/img/smilies/icon_scratch.gif If they’re different finishes, they will have different grip. Is the building you take your classes in climate controlled – like do they use a dehumidifier? That kind of stuff has an impact, too.
There are several other threads about how to help with grip – both on hands on stuff to put on the pole. For hands, there are: frequent handwashing with soap, Mighty Grip, Tite Grip, Dry Hands, and rubbing alcohol (those are the common ones). For the pole, rubbing alcohol and candle wax come up a lot. There’s actually a thread started by Neke entitled "Insane rantings of a madman?" asking about the coke question – general consensus being that no one here has really tried it but cola may actually be bad for your pole.
Browse around a bit and you’ll find that this is a frequent topic https://www.studioveena.com/img/smilies/icon_e_wink.gif
