What are your favorite weapons to fight specific monsters? Just wondering what matchups you get excited for!

I’m currently in love with KS IG and bagel is now my favorite monster to fight with it.

Will include a look at the season 11 monsters and upcoming updates

I currently have focus 5, raw power 2 and critical ferocity also at 2. I'm using diablos bow almost exclusively and I'm building the B Diablos at the moment. I have limited time and resources so testing is out of the question for me. My question is, it better to abandon Raw Power and just do Crit Fero 4? (That's the best option I have atm w/ bishaten helm).
