I tried the 78 the other day and also the quad 84 in comparison. The wind was qyite strong and my 4,5 sail a bit much from time to time.
As a 87kg average wave surfer who spend most of the windsurf time on slalom equipment i felt that the kode wave was faster and overall more fun compared to the quad. Main reason was the effortless glide, speed and upwind perfornance. The waveriding on the 84 is a bit easier, especially when you want to turn tight.
However i love the energy the kode wave does delivery when you cut into the wave, it just makes me smile. That is also why i went for the 92 kode wave, fast, controllable and with a good wave performance.
If you are light and sail mostely in well powered conditions with clean waves, go for the quad.
Mquspots do usally have a lot of current and not very strong wind on the inside, hence i went for the kode wave.
Both boards deliver but you'll have to get dialed in on both. Enjoy!

I think Sinobi has summed it up pretty well. This is a really fun board to sail in mushy condition and it jumps higher than anything else I have sailed. The wide tail means that when you do hit the lip you have a good chance of getting airborne even wave riding in crappy conditions. I have it set up as a Twin on all but the most onshore days. As a single the looseness and slid starts to disappear and it feels more like a short frenetic FSW, great for river sailing on extreme days and good for XL jumps but not as magic on the wave. In single fin mode the 77 will carry a 5.7 easily but set up as a twin it does not like to be pinned down to much, a 5 is as big as I like to go with this set up. I am 75 kg so the 77 is a pretty big board for my weight, waveriding in 30+conditions can get a little messy but now I have a Quad for those days.
