I have shaped and surfed my own Paipo - a mini 4ft Alaia - that you ride like a bodyboard or Macca's tray. Definately a wierd feelig paddling a board that won't float your weight, however if you treat it like you are bodysurfing, when you catch a wave, it just takes off. I've never been any good at catching waves bodysurfing, but with the Paipo, that all changed. The noticable thing is the speed you get from it.
The best thing about it though, is I made it by hand, without power tools, and learned a lot about what makes a board work. It makes you realise that you can make something that surfs, and do not need to spend big money to get out in the waves. The smiles you will have when you ride someting simple that you have created yourself are well worth the effort. Also spurred me on to shape a twin fish for my kids. Work in progress already.
And my sons love it, they have a ball when they go out on it.
I'd reccomend everyone with an interest in the surf, have a go. It's an amazing way to learn, create and be stoked. Make one for yourself, make the next one for someone else who needs to get stoked.
