You know, I have been thinking about my response...
Dropping 20 litres and 7" may be too big a step. Even though the 8'7 would be good if you have been surfing/paddling a reasonable amount, if you are still going up the learning curve, perhaps you should be more conservative.
Thanks CSE
My too thoughts are
? the 8'10 may be too close to the 9'2 flow
? the 8'7 may be a drop in volume. A bit more than I can handle
need to demo I'm thinking
