Followers with follow Liker

Hello,

I would like to have your opinion about a "problem": with Follow Liker twitter, for the followers part, I take a lot of big accounts relevant to my niche, and I follow the followers of these accounts.

So, I only have a very huge list for the followers.

Do you think I need to refresh my followers, and to make several different lists? I use list A this month, list B the following month, list C, ..., and then I go to list A where accounts will have new followers.

Or do you think it's ok to do like I do?

Thanks

Anybody?
