Yeah, it really depends on who's writing him at the time. One scene that really stands out in my own mind and I kindof revert to when I think of how strong he is, is when he's standing beside Nova. They're at some kind of steel reinforced door and Nova's debating about how to get them through it. Spidey sighs, walks up to the door, and yanks it out of it's mounting. The door, after he has it in mid-ait, looks to be close to a foot thick. Wish I could remember where exactly that's from. I *might* have it upstairs in my long-box, actually. If I do, I'll post it.
