ONLY AS A RULE OF THUMB 00.254 flex is about one lb in relative stiffness.
example of above and this is a estimate as each brand varies;
17.1-16.4=.7/.254=2.7 lbs estimate

The answer was 2.7 lbs difference and how it was figured for everyone as reference?
In most cases 2.7 lbs is not a problem and can be lightened by 1 to 2 inch increase in grip!
