What? Why are you taking me here? What did I do?
Oh, hi!
If you don't mind, I'd like to ask a question, then answer your question.
How do you know you need +0.25"?
Now, to answer you question: "Would I advise against it?"
No sir, I would not.
However, please be aware of the additional changes you'll see besides the obvious length change. They are (and I list):
Your
clubs will be 4 or 5 swingweight points lighter
Your
clubs will play 1.5° flatter
Your
clubs will play marginally stiffer
Your
clubs will weigh 3-5 grams less
Just so you know what you're getting into.
