PVC or steel dolly track?

Getting a dolly at some point was something on my list but not a priority. Then someone had a dolly platform on local Craigslist for a couple weeks with no takers. I finally emailed & said I'd pick it up right now & give him $50 so it's mine now. It was a $700 platform if new and in very good shape with wheels & trucks that looked new. Now I'll be putting together some track. Looks like 1.5" PVC, steel, or aluminum is what I'll be needing. PVC strikes me as being easier to work with, would have a bit more flex (for exterior uneven surfaces), and would be less likely to get permanently dinged as metal. Anyone with experience with PVC as well as metal track that might have some feedback to offer? Also wondering about going with 1.25" It looks like everything will still clear and that might give me even more flex where needed.


Any help appreciated.

Thanks!



I didn't find the right solution from the Internet.
