[quote]It does look baggy but that was mostly because the sail was old and baggy/full to begin with (new spi's are much flatter).
With the mainsail on it looked a lot better though since it practically operates as a backstay. (quote)

Chip at Whirlwind makes a mast head spinny for the 17 so I will probably go that way and Hobie Phil has some great results with the 17 I think.
I do not have a jibbed 17 and feel that a spinny would be more fun and result in a lot less spaghetti on board.
My other choice is a hooter which would be very flat.
