Hey,
Ridden with both for many years, sometimes i only put rear one on.
As a Old surfer was always keen to try strapless 10 years ago when i went away from twinnys , def gives you more surfing feel ,but certainly a lot more loosing your board when you first start.
Dont let the wannabees Talk you in to strapless if you dont want to , experiment try with out both maybe put the back one in whatever you feel is right.
I ride now strapless in nice clean waves and when its messy put the rear strap in , i am 60 this year and getting a bit older and hip plays up so bugger it , been surfing since i was 15 and kiting since i was 45, enjoy the waves, you will always have the so called experts telling you there own option .
Just enjoy the stoke
