i've an old 71l starboard evo IQ which i've only ever used as a single fin setup. Great fun to ride, light fast and responsive
Would 14.5cm be too small for the twin setup? 4.7 to 4.2 weather for DTL
Can try and see but just want to be in the ball park so i dont spend my sess swapping fins

I think that board was stocked with twin 15cm, so 14.5cm will be fine if you're not too heavy.
If they have a wide base they should work . I use the upright MB twinzers in mine at about 16.
Shame twins fell out of favour ,so fluid on the right wave ,and fizz through turns.

Think k4 leons would work well to.
