These are the GMSTs that I use. It is intended for balance with Tamriel Rebuilt and Project Tamriel, and it also makes the game a little harder.

Tamriel Rebuilt, Skyrim: Home of the Nords, and Province: Cyrodiil makes the game almost 3 times its
original size. I have made training cost 3 times more, and training take 3 times longer.
Previously travelling did not take much money. I have increased the cost of travelling including mages guild travel by 10 times. From Seyda Neen to Balmora was only 8 gold. Now it is 160 gold.
Each probe has a different untrapping value, however the game does not have any difficulty setting for traps. I have set the untrapping value to the same as the unlocking value.
Personally I think NPCs greet you from an annoying distance. Now they only greet you from 2/3rds of that distance.
Sneaking is now lowered like the popular Lower First Person Sneak mod.
