The supplier makes no difference. They all carry the same stock from the same factory. Pick one which you are comfortable with in terms of communication. Personally I do not like the Big Bang Senna, but thats just me. You will learn there is just 1 version for each variant out there I think, so "best" does not apply here. You just need to pick the type you like (CF, PVD, ceramic etc) Go use the search bar and read up a little more please, newbie. You will find info to occupy you for a while. Welcome to RWG.
