Hi - I currently have an I20 and previously had a P19 + hooter, both of which I often sail alone. I have righted my P19 several times alone with the aid of the large Murray's waterbag. It works (I am 200 lbs).
One other thing to consider is GARY's soloright. He has kept working on this for several years, and regularly rights his Mystere 6.0 solo (I think he is about 160 lbs). Just last week he demo'd a new version and successfully righted a H21se solo (that's right, the monster boat...). Check out these photos at:

Sail fast and have fun,
