I was debating the same thing last week (same wheels but 17x8). I decided +45 because I don't like slam/poke/stretch. +35 doesn't look too bad, but with +35 you're stuck with it. Getting +45 you can always get spacers. I'm mostly content with the stock front offset, but the rear could use some help.
This is the best pic I found of the +35 front poke. Check out his
journal for a few more pics.
Not sure if you've seen
this thread, but I like post_break's offset. Looks like he went with +45 and added spacers in the rear
