Far from back-patting, you're being downright insulting. But that's fine, my "nerdy spider-fanboy wetdream" was a two-minute write-up that I thought I would share along with Horatio's scenario.
I find it interesting that you're wholly willing to accept that Peter could find and disable this failsafe in his suit, but it then becomes completely implausible that he could find a way to turn it on Stark. If Stark is indeed "ten times the genius Pete is", then how did he find and/or disable the failsafe in the first place?
I think you're being unfairly and unnecessarily critical. If you don't like either of these write-ups then more power to you. But to come in with both guns firing is a little bit out of proportion to the original posts.
