Let's spread the longboard stoke. I am 34 now and started longboarding at 30. Have surfed a shorty for probably 20 years. I agree owning a lOngboard opens doors and gives you more surf time. I find I now am scanning the forecast for glassy waist high days whereas before I wouldn't even bother. And waves that are a little to fat and slow for a shorty can be super fun on a longboard.
At the moment own a FireWire longboard which is fun, but a mctavish purchase is imminent.
It's amazing the glide a longboard can give. If you pick the right line on a wave it can just fly, even when it's small.
Rant over.
