Those bow sets look solid-- good mix of offensive skills, especially with focus. Even the kelbi set, I admit, has a good mix of offensive skills that I don't usually see with most kelbi bow users.
Do you by chance have a +10 power coat talisman? That would provide more flexibility with using other bows while maintaining the nice +50% raw dps boost from power coats. The Bamboo Kaguya set, for example, can be mixed to get element attack up, focus, power coat add, awaken, weakness exploit.
If you're open to using other bows, I recommend aquasteed harp as a solid water rapid set (with loadup minimum), ala bow for dragon pierce (pierce boost, focus, eau minimum), or fire rapid-focused gold rathian bow. The last one only needs fast charge+5 talisman to get load up, normal s boost, focus, power coat add.
