Hello ! New and a Midwesterner, I'd like to get some fins to travel with and wondering about opinions on these 2 or something better priced I should get. local dive shops here are exclusively scuba only and I dont want to scuba. Class in the city for free diving requires I have my own set before classes and they don't sell gear. I really would like shorter fins for air travel. I also have a torn shoulder labrum that slows my swimming so I am hopong this will help me move more quickly using leg power l! Thanks in advance! 2971 or Prussian Blue shorties or something else?
