After my Roxy failure, I made two determinations:
1) Don’t get a soft-top. While it would give a little if it were to sail into my noggin, my knees couldn’t take it. After an hour on the thing, they looked like those of a nine-year-old who had fallen off her bike.
2) Don’t get something too narrow. Admittedly, trying to remain upright while sitting on the board was a fun way to stay occupied when waiting for a wave (I mean, who doesn’t like a challenge?), but it wasn’t so fun when I’d miss a wave because I had inadvertently rolled over right in front of it.
