i have tried to put a berg-larsen (the metal one) into it.
judging from the sound, the horn gave a rather sharp, pop like sound,
the vandoren gave it a jazzy feel, more relaxing type,
when i borrowed a tenor mpc, it gave out a rather lower dark sound (i dont know the brand of that mpc)
thinking from what i experienced, the horn is really a hybrid of a tenor and an alto. it really depends on what i want to sound like or what i want to feel when i use the horn.
for now, since i have my mark VII as an alto horn, im going to try to put a tenor mpc, maybe a berg-larsen to the c-mel.
once again milandro, your advice really did help.
