You need to decide if you want as much as possible bass or very open treble
The wider the bore the less pronounced the bass will be, and the narrower the bore the more closed the treble/stage will be
but let me tell you that Feaulle H570 Latex Tips and Tri Clarion Tips work perfectly fine with Legend Evo.
Both have a wide bore for open treble and soundstage and they still got plenty bass
H570 seals better therefore probably a bit more bass.
I tried a lot of tips with Legend Evo as I was also looking for the most open treble because Evo is kind of limited in that regard.
The two above mentioned are my absolute favourites so far!
Order of preference: BCD, treble, bass. I have a wide bore with nice treble (Spinfit 155) but the BCD is much weaker than narrow bores (Final E, Azla Crystal)
It’s been tricky to pack BCD and treble together. I can see why EE took so long to get to Raven -)
