A lot of people are going with the Assist cat with Boomerang Pro, AUL, Big Boomerang, Piercing Boomerang and Emergency Escape as the best Boomerang focused cat in the game.

Personally, I prefer the Gathering cat with the same skills/support moves. The only differences are the ability to steal up to 3 items from a monster, instead of trapping/poisoning them and Gathering cat can get it's support moves a bit earlier, since Emergency Escape only needs a Cephadrome to unlock, while Piercing Boomerang needs Narga.

Probably the best way of farming monster parts solo is to play as a Gathering cat, with 2 other Gathering cats as support. Against a Rathian for example, 3 carves if killed, 1 if the tail is cut, 2 steals from each Palico, up to 3 from your Prowler, plus rewards. And stealing can get rare items, so up to 5 more chances at rare materials is nice.
