Hi Shingly, you will find the Quads quite different to a single fin in the way they ride (particularly vs the FSW). The single fins tend to ride a lot higher in the water, more free and more off the fin, whereas the Quads are more planted in the water and ride less off the fins.
Our wave test will have a full comparison of single vs twin vs quads, but basically, you will find the Tempo a bit more wave orientated than a FSW. Almost the same as comparing a single fin wave board with a FSW (freestyle wave), but the Tempo turns a bit better on a wave.
Thanks,
Adrian
