Anyone fishing Great lakes, Rayburn, St Clair have in likes or dislikes between these models besides speed. Id really like to have the 522D but I can find a 521C for about 10k to 15k cheaper. Are the 522D really that much better on the big stuff. Granted Ill prob never set out in 4ftrs on Erie knowingly just because I have a deeper V but even on the days that they call for less than 2' or 1' to 3' are not that comfortable in most bass boats.
