Yes, I agree. Everyone is struggling a bit with this.
Also for me @87kg is the IS122 already for several years my most used board.
Only 2 sails, I use on it 7.8 & 8.8.
As it is my most used board, I would like to replace it with something that has the same capacities and even better of course. Logically it has to be the IS110, I think.
IS87 / IS101 / IS122 / US147
