Replying to Do Head Skis run true to size?

I'm looking to get new skis this year since my 09 Suspects are starting to fall apart. I am looking to get a bit of a wider ski this time around because I have been doing more all mountain over the past few years and I have narrowed it down to two skis based on price and reviews; Head Oblivion and Rossignol Slat. I read that the Rossingols tend to run a bit shorter than the advertised length, does anyone know if that is also true for the Head's?

Also if anyone has used either of these skis, what are your opinions on them?
