Just got myself GS Pro to go with my Mevo+ to play more than just the E6 courses that came with it (as much as I love links golf and having St. Andrews and Troon is amazing for that, the number of courses on GS Pro is just too good to say no to.) Huge fan of the Cabot courses and the Bandon courses as well. An American links-like pair of courses I'd recommend if you want to practice at more of a midwestern elevation close to my home here in Wisconsin would be Sand Valley, and Mammoth Dunes and I'd recommend both those to links lovers looking for something a little different. I also enjoy practicing my home course here and getting that advantage on my playing mates (The Meadows at 6 Mile Creek in Waunakee, WI; it's a nice, fairly typical southern Wisconsin course)
