I have a difficult choice to make for my third recommender (Letters 1 & 2 are both from people that I've done research with and I think will write solid letters).
Recommender #1: I took a course from and got an A, and I have been working for them for a little less than a year. I think I have made a good impression during my work in their lab. I have not had this person write a letter for me before, but they have agreed to do so for my applications this season.
Recommender #2: I also took a course from and got an A, but I have not done research with them. However, I recommender #2 has written me a letter before, which I believe was very strong. Recommender #2 also has connections at at least two of the schools where I plan to apply.
So, I am debating between asking one of these people to write me a letter at the school where Recommender #2 has connections. Basically, I need to choose between a known strong letter with connections, but no research, and a letter of unknown strength but can say more to my research potential. Has anyone been in a similar predicament before? Which would you choose?
