Definitively the Quobba fins. The M (Orange) should be perfect for your weight. Their added acceleration in turns and increased top speed is addictive.

Ok so tried the Quobba fins. Waves were 3ft clean slowish with outgoing tide reef break.
They feel like a diesel, slow to get going but once going they keep going. Bottom turn felt bitey, top turn again slowing down before going...
They're a funny shape with space between board and fin bottom...not sure if that's how it's supposed to be???
Can anyone with Quobba set up take a picture and share?
I had to quit my session 90min in when a surfer decided to crash into my board and did damage....a shame as conditions were great...
Aloha,
