I have a 2013 125ltr rocket std and love it. I bought it new and while I contemplated it for a while it was a good choice. I'm hanging on to it as most people do.

It is great in the bay chop and as mentioned has an awesome range from light winds to to when the wind picks up to a point. My mate has a 115 rocket a couple of years older and I have used it and I also liked this board. But I am not good enough to notice a few percent improvement at the top end year to year. Maybe if I was to hop on one from several years ago the few percent each year may add up?
I am considering a 106 3S to replace an old JP FSW. But like the rocket you rarely see one come along in A1 nick second hand and they are not cheap new.
Good luck finding yours.
