new x poles for class, chrome or titanium?

hi there just wanted to ask your opinions on several x pole finishes. i want to buy about 4 new x poles for my new class venue and im undecided on what to go for? In my other venues (i own my own pole company) i use 50 mm stainless steel poles (non x pole). I need to go for x pole for one of my new venues and again am used to teaching on 50 mm chrome. I would like to give my students a choice of different types of pole in class so was thinking of perhaps having one 45mm and perhaps one titanium gold. How do these compair to the standard 50mm chrome? is titanium more or less grippy? and is 45mm harder to perform inverted moves on? 🤔 i unfortuatley have never had the pleasure of using either a 45mm or any finish othr than chrome or stainless steel, so your views would be great! thanks 😀 xxx
