Just wondering if there's any notable differences between the Surge 1 and the Surge 2 apart from the added window?

If you are talking about the PPC wings ("ver 2" comes in both non-window and window version):
Quoted from nzfoilcentre.co.nz website
Updated handles
Updated wrist leash with brass swivel
Extra reinforcements on canopy tips
Handle position adjustments
(I have also seen harness line loop attachments on wings around so may be an added feature they forgot to mention?)
