Thinking of picking up Squeezer again, tips & help appreciated

[Picle]

So for context, I did play Squeezer at one point for a team. But now I have my own team and my coach suggested that I try out Squeezer again. The reason I initially dropped the weapon was that it was ridiculously hard to get value with it, with things like bad paint, having a hard time maximizing its fire rate, aiming while maintaining said fire rate. Overall, I found this weapon really hard to get picks with, I also feel like I have to learn Squeezer from square 1. If there's any squeezer players who can possibly give me advice/help/tips on this weapon, it would be appreciated
