Need help for a venti main dps team.

Hi, I want to do a venti main dps team but I don't really know how to do it so I have a few questions that would really help if you can answer them 👍.

I have: -Durin c0 with his best weapon -Venti c0 with his best weapon -Faruzan c6 with favonius warbow -Bennet c5 (can activate c6) with sapwood blade

Question 1: Are all the weapons good or should I give them something else?

Question 2: Which artifact sets should I use and which stats do they need?

Question 3: Should I try to get durin c1 or venti c1?

That's all the questions I have, thank you if you can help me. If you need to know more informations about what I have (about the weapons for exemple) or have any suggestions that are not in my questions, don't hesitate to tell me 👍
