40mm to 45mm and finish in AZ!!

I haven't seen much talk about the 40mm...which is what i have in chrome..i called xpole today to see if it was possible to switch some parts to be able to get brass with out paying all over again..she said i could..i think brass would be a better finish considering my sweaty weather here in Az..tite grip itac corn huskers isn't really doin it :(....i fig also once xpole in fall comez out with the PC pole ill snatch that up in a 45mm..hoping that between the finish and a tid bit bigger mm would all over improve my poleing...idk..I'm hoping to some good thoughts and how the 40mm differs from the 45mm :)
