I'll reply from the title of the post, "Main safe on Hypixel?"
It never did or we don't have people saying they got banned (+ proof), so no it won't ban.
Reach will NEVER be as safe as BackTrack
FakeLag Dynamic doesn't add much to backtrack... if you have 150ms, the server consider you can hit the previous positions if it's not a bad ac.
20% Jump Reset Velo is a good Main safe
Sorry bro were sosry to tey held u dkono sry pls ;(;(;(
3.4 reach is too high, even if you're 250ms
Use 3.1-3.2 or BackTrack
BackTrack let you hit a previous player position, anticheats can't flag it or they get a lot of falses flags, it is a good reach alternative
