Hello! I bought 2 Head MicroGEL Radical OS rackets a little more than a year ago. Great rackets except... the other day I happened to notice that they aren't the same length! One is about 1/4 inch shorter. I haven't brought it back to the shop yet, but I'm a little concerned about what the answer will be. Don't know how long the warranty is if any. Anyway, the question is, what kind of difference will that 1/4 inch make? I'm about a 3.5 player so it's not like I'm making a living with these rackets. But seems like if it says 27" on the racket it should be 27", even if they don't make the model anymore and I bought them on closeout. Any thoughts?
