The crown hat is the best hat for this level. It is very useful because there are miscellaneous mines placed throughout the level, and you will sometimes hit them. Also, during the long stretch of mines, you can just walk through them rather than having to shoot them. If you don't have crown, you should use propeller hat.
I recommend a high speed and jump. There are many 4-5 block jumps in the level and most of the level is straight.
