To get this with Binding, what approach would be proper?

1) assume 10 seconds based duration (page 101 under "Range, Area, and Duration for Advantages") and take Extended Duration 1000x +120% to get it past 2 hours

2) assume unlimited duration and take Maximum Duration (page 15 of GURPs Power Ups) either "Up to 1 hour -10%" or "Up to 12 hours -5%" ?

Given that the description of Binding states:

I would assume a 10 second duration and take Persistent and Extended Duration for how long you want it to stick around. That is, if I was approaching it from a simulationist point of view. As a gamist, I'm more of a "it sticks around as long as needed for the plot". No #spideywhities. :)
