For NCAA college players, do they have to pay for the strings and the stringing labor, or are they sponsored? Is there an allowance for the strings or how often they can get new strings? I often hear about various colleges using a particular brand of string, I wonder is that just because it is free, and the other strings need to be purchased, or if there is actually a reason the string is preferred. Some I have tried have been very mediocre compared to say luxilon, gut, or other premium multi. I've heard of players packages where they give you x number of racquets and or a bag/apparel for a discount but if they provide strings can you use a new stringjob every ball change like federer/nadal, or is there some limit to how often you can get luxilon strung per match?
