Puzzle #136 - Stripes and... Stripes (Haisu)

This Haisu puzzle is fairly tough going, from what I've gathered. Haisu is a creation of TheGreatEscaper with the following rules:

• Draw a path on the cells of the grid, starting on "S" and ending on "G". The path must visit all cells. A number N in a region means that the path passes that cell on the N-th entry into the region. For example, a 2 means the path must pass that cell on its second entry into its region.

I really, really hope this puzzle is unique- I kept finding alternate solutions while constructing and every re-test found something new I had missed. Even the one after not finding any ambiguities found something new that, fortunately, contradicted in short order.
