I have a battered old TSS4 and a few bait-runners is it the 6500 you want to compare to? i can have a look if you like
but i am guessing that the TSS4 would have the bigger gears as the 6500 has all the clutch and wotnot in the body as well
as the gears.
Are you interested in selling one of the TSS4s are they all in good condition? i am writing from Australia just so you know
that i am not around the corner.
They are excellent reels.
