Thanks for the kind words.
Unless a pitcher is a rookie or missed the previous year, I usually do not update pitchers during the season. When the season is over, I will incorporate the changes to their pitching repertoire when I start my edits at the end of this season.
As far as the 2 Seam/Sinker goes, I prefer the 2 Seam to the Sinker because according to Brooksbaseball.net, most Sinkers have more horizontal movement than vertical movement. Montgomery's Sinker has almost twice the horizontal movement than vertical movement.
