Thanks. I think that sounds good to try a 5.0 on the 71 quad. The springy pop of the quad is pretty good as you mention; quite a satisfying feeling.
For cross-shore wavesailing, I'll only ever be on the quad71 and from 5.0 down. For bay conditions, Flare98 5.4-5.0 then Quad71 5.0 down.
I think it sounds like the Flare 98 will cover me better for 5.4 to 5.0 conditions.
The Kode86 needs power so reaches its prime for me at powered 5.4 to powered 5.0 when I could be on 5.0 with the 71 anyway.
