when there is lots of graphite showing, or when I get a new string job and it plays the exact same. If you change your grommets several times they it can really add some life to your racquet.
From the number of "allure" and "experiment" responses which are basically the same, it looks like there are a lot of racquetaholics like me out there!
I have changed racquets sparingly over the past decade. Leading up to the racquet I currently play with, I only changed racquets over the past 10 years because the old ones were causing my tendonitis to act up due to their stiff flex.
it's like a bad habit, like smoking or alcohol. how often do you change the racquet is a large difference. the fact is that you do what is missing in life, and you're trying to get this through the purchase of a new racquet.
The only 3 racquets I liked were the Prestige Pro/MP and the Pure Storm Tour. If i ever did switch, it would be an endless rotation between these 3 racquets every month. Easily able to give me a good scratch on the head to think about which one to keep.
The only reason I ever switched was trying to find a similar racquet after I eventually broke my original racquets. I learned my lesson and I've bought plenty of M-Fil 200's to last me a good long while. Good thing too since Dunlop's 200 series has changed so drastically. Recently I did get a few 4D 200's which play nearly identical to my M-Fil 200's so I don't really consider it a racquet change when I finally get to use those frames years from now.
Whenever something sounds exciting like when the Steam 99S came out, and you have to try it yourself to have an opinion on it. Great racquet but went to strings too quickly and awesome for topspin hitters but not for flat hitters like me. Went with modified Steam 99 non-S and hitting really well. Awesome frame with additional silicone inside handle.
