I have owned the Blackland Dart, the Blackland Bird SB, and the Blackland Bird OC. All three are great razors and great shaves. I sold the Bird SB and the Dart and kept the Blackland Bird OC. Initially, with all three razors, I was disappointed that they seemed to be too aggressive. However, I was so satisfied with the closeness of the shave that I continued to work on mastering the proper technique needed for each razor. The difference in feel between the SB and the OC is barely noticeable while the OC is a slightly closer shave. Finally, if you want the best bang for your $ for a super close shave the Dart cannot be beaten in the Blackland DE line.
