Is the aolong v2 faster than the zhanchi
I have an Aolong V2 which I used as my main for a couple of months and recently bought the ShengShou Aurora and a Dayan Zhanchi. The Zhanchi turns lighter, with a lot less effort. Both are on par with speed right now but that's just how i made them, used higher weight lubricant in the Zhanchi. The Zhanchi has a lot more potential to be faster. The ShengShou though smooth needs the most effort to turn out of all three. The Aolong cuts corners with more ease and pops alot less then the Zhanchi. Despite that I use the Zhanchi as my main now.
If you can afford it, just buy both ;-).
