I'm going to redo ours, too, at some point. Version 2.0 will include:
-Flap cover over zipper to reduce water coming in.
-Attachment points at mast and boom end to keep sailpack taut
-FOUR lazyjack attachment points instead of three to support the pack better
-Lazyjack attachments will be loops or something on the sailpack itself, not on the batten/pvc pipe. The current pvc pipe arrangement is not stiff enough to prevent sagging along the length of the sailpack.
-If I feel like it, maybe some blocks to have single line zipping/unzipping of the bag.
-Also considering mesh "windows" in the side of the sailpack to improve drainage and air flow.
And, the next one will be PURPLE
