Technique overload is definitely a concern. Sometimes a position will still be a "work in progress" causing me to get brain locked when I hit the position because I can't decide which way to go. Personally though, I love reading tons of instructional books just so I have a mental Rolodex of techniques to solve potential problems that I may encounter with different grapplers. I refer to it as a "seeding process" where I am aware of techniques but I don't actually know them. Once I get stuck or need a solution to a problem then I can think, "Oh, that was an x-guard sweep. Saulo had a section on passing that technique in his book, I should probably review it."
In that respect, having a wealth of instructionals at your fingertips is immensely helpful even if you don't have enough time to learn it all.
