Just so you know, you can also just buy the 45mm pieces from xpole. I sold my original 50mm to get the 45mm and when I called them to order, the rep told me that they also sell just the A & B poles, extensions, and the adapter for the 45mm. Basically I spent time looking for a buyer and delivering it, took a loss on it and the extra I had to pay for the new pole was just a little bit less than if I had just bought the additional poles outright. And I would have had both poles to interchange. Which ironically enough, after I bought the new 45mm, I found I didn’t like it as much and ended up ordering just the poles for the 50mm 🙁 So make sure you like the 45mm.
