LOL blame it on the "Hot or Not" thread! I amuse myself sometime seeing how stupid I can be...

I think topflight's concern is genuine. You have put countless miles on with your current setup and to change it the week of the century 'could' cause much longer term damage outside of a sore knee. Just offering some food for thought.
And regarding food, make sure you sports nutritionist has your training plan for review and to help build a plan. Like I have told others when working with nutrition, follow the plan... Don't make substitutions thinking that it won't make a difference, it will.
