Possibly Buying a Pole Soon....Have Some Questions

Hubby and I were talking last night and he mentioned that he would love for me to get a pole before he deploys and we'll call it an early X-mas gift. So, of course I was super excited and since his tuition this semester wasn't as much as I thought it would be, we have some extra money. I've done a ton of research but still have a couple questions I was hoping you ladies could help me with. I'm 99.9% positive I want a X-Pole. Since my husband and I will be moving in a few years, I don't want to do anything to our ceiling (i.e. bolts, screws, etc.) that might make it difficult to re-sale. My studio uses brass poles and that's what I'm use to. I looked up X-Pole and saw that they sell the Chrome and Titanium Gold. I was wondering if any of you gals had experience with either or both of these and which you would recommend with me coming from a brass pole? My studio also has 50mm and 45mm poles. I use both and rotate between the two depending on the moves. I tend to learn more complicated moves on the 45mm because I have tiny hands, then move to the 50mm when I feel ready. I'm not sure which size to get at home. I am going to continue taking classes at my studio, so if I go with the 45mm, I can still use the 50mm at the studio. But at the same time, I feel like maybe I should just get the standard size and be done with it. Thoughts? I think that's all the questions I had. Any suggestions/advice/tips you guys have to offer, I would greatly appreciate. I would really like to be able to order one this weekend, if possible.
