Like Valk mentioned in a post above - I got the .105" for the same exact reason as you did several months ago now. I am not biased either. I love all the Gator Magnum lines, but square is a hit or miss line when it comes to feeding form certain heads like the Stihl 25-2. I use Crossfire for my daily trimmer which is my Husky 223L. It will bog slightly in heavier growth with the Platinum ST, but is runs like it's way bigger than it is with Crossfire.
