Thanks again Ola,
ET is indeed an extremely nice board in waves. I've tried the ET74 at it was just amazing, the way how easy turns vertical on the face; it was like i was riding on rails (literary), however I don't consider buying one, I like the single fin feeling as well, however requires more commitment.
Considering all the input I've got from you I probably have two realistic options
1. Keep my current EVO 80 for a while and have a Kode 74
2. Have a Kode 80 and an EVO 70 (I do like the EVO feeling, so Scotty is not alone in this

- however I like the way how easily the Kode jumps);
Another option is to get rid of a few kilos

, probably I can get down to 78 from 80, not too much, though... and change my NP Combat's to a much lighter S1's.
Thanks again for your time, it was very helpful.
