I just tested both reel spent 2 days with both reels on the same St.Croix Avid rod and same line.
Both cast very nicely but it the Stradic Ci4 seem much rougher retrieving the line back in. You hear the gears and the handle seems to have have "grinding" feel to it. The EXO Pti was much better retrieving the line.
Has anyone actually tried both reels?
