Viable fracture comps.

What do you guys think is the most viable fracture composition?
Jett is the main duelist and Breach is the preferred initiator. However, I've seen a lot of teams play Viper, Astra and Brimstone as the primary smoke options. Which Sentinel is the best and what's the 5th agent in your opinion?

Kj and cypher are the best sentinel imo some team uses sage too
initiator should be the 5 agent

2 initiator combo can also be used since the map is quite large

Jett
Reyna
Yoru
Raze
Phoenix

Kayo might work in here imo

i have seen a lot of sage, brim, breach and jett in Fracture however, we wont know the good comps until champions. Also I highly doubt any teams are going to pick fracture much because they havent played that map much in pro games for the required confidence to pick as their map pick

jett, viper, cypher, and 2 of [skye, sova, phoenix, breach].

explanation:
jett - obvious, best duelist in the game
viper - imo better than the other controllers on this map bc of her wall. She'll need lineups for orbs and postplant tho, and if you don't have/can't find those, Astra might be better.
cypher - should be the best sentinel here. With 4 site entrances and so many passages, the 2 trips are insane crossmap info gathering that KJ just can't replicate.
skye - just an all-around great agent atm, insane info gathering, fits on every map and I don't see why not here.
sova - with 4 ways to come on site his arrow is as useful as ever. I don't think this is his best map, but it doesn't need to be for him to still be extremely useful.
breach - his flashes are really good on this map, you can blind into the sites from quite far away, and the quakes and aftershocks are good too since there's lots of cheeky corners and verticality
phoenix - might seems like an odd choice given his current (lack of) place in the meta but imo he's the best 2nd duelist here. 4 ult orbs will keep arguably the best ult in the game online often and his wall is plenty long enough to cover most the passages and sites.

Jett
Astra/Brim
Breach
Sova/Skye
Cypher

Breach/cypher depends on what you want
Sova
Skye
Kayo
Astra
Works very well in ranked if the skye is good

[IMO] Astra, Breach, Viper, Cypher, Jett

I feel like the double smokes is almost a must have, they are super powerful for defaulting and executes and also defense. Breach is obvious, and Jett is Jett, then it can be rounded out with a lot of agents, but I believe Cypher is the best since he can take even more map control with the camera, however you can also try Killjoy, or maybe something like Sage/KAY/O for a different look, or even Reyna/Raze if you're looking for a more aggressive style which maximises the rounds you take on attack

Viper breach jett skye cypher

Breach - Must agent in fracture
Skye - Still too OP
Cypher - Good for defending
KJ/Sova/Viper - KJ if you want to more defensive. Sova has much bangable spot with some tricky lineup not the best map to play sova tho. Or viper if you need controller.
Jett/Reyna - Duelist and IMO Jett not the best duelist in this map and Reyna better.
