Hey Breezer: I dont hate my Calcutta ,a sweet little 250.Like you I figured I should adjust the brake weights and removed all of them.Disaster the spool spun so fast I couldent keep up with it.I went back to the factory settings and they were perfect for 3/8oz .I dident even have to change the settings for 20lb powerpro.That stuff is dynamite it feels just like the old silk braid but one hell of a site stronger.
In case anybody wants to start fooling around with the break weights on a Shimano just make sure you adjust them in pairs selecting directly oposite weights.
