Of the four options in the Tracker, I'd go to the 4" Titanium Tracker, and with the .357 as the pick thereof, with second-place being a toss up between the .44 and .41, with the .44 probably slightly ahead simply for the .44 Special capabilities.
Darn you guys.
Now I am lusting after a 4 inch Ti Tracker in 41 to load with "41 specials" for carry. Dang it!
