I have trained my own model based on cifar10_train_test.prototxt for my image database with high accuracy.
Hence, I think bvlc_googlenet/solver.prototxt could work well for you.
Of course, you should modify the num_output to be equal to your number of categories.
Then, you can try to modify a little bit in bvlc_googlenet model to improve the accuracy on your database.
