Timo is right on the money there
Your thread should be called "please post weights of your bio 200 tour....."
I'll measure mine but will not read too much into it.
You already know that your pair are close so you already have your range!
Also, there are other factors at play like SW, bp, blah, blah, blah so even if you had the racquets in this range, you could have other variation.
Nonetheless, you have to find out how much variation that you can tolerate in reality, i.e., getting on the court with the different variables
Have fun dude!
