For me I dont like foams, I use sedna earfit L size for my BL-03, they have slightly longer nozzle like spinfit, but they are wide bore and shaped like spiral dots without getting lost of treble energy and blur imaging due the dots
By any chance, do you know the difference between the standard Sedna and light sedna (transparent)? I'd guess the material is softer but I'm not sure if there's another difference.
