How tall are you and how many serves do you average in a match against someone of Eyad's ability? Ideally those numbers will be 6'3 and 10+. S&V games are going by the wayside, because it's easier to hit passing shots with today's tech. If you really want to improve, you might want to consider altering your style unless you have a very menacing serve and are tall enough to make passing shots extremely difficult. The problem with S&V is that your room for growth if not exceptionally tall or with a gifted serve is limited because as you move up the ranks you'll meet more guys who can reliably top spin lob, hit nasty passing shots, and won't be phased by your serve. With a baseline/all court game, you can incrementally improve, but if you S&V, if someone has your serve down, no matter how good of a volleyer you are, you're probably screwed.
Will a coach not recruit you because you S&V? Nope (in most situations). Tennis coaches are all about wins. That being said, if there's two guys of equal ability and one has maxed out his potential at S&V and the other person is an all court guy who has more chances to improve, he'd probably take the other guy.
So essentially, I wouldn't tell you to switch, but S&V can be limiting as far as development goes. I don't see why you wouldn't develop your all court game while picking your spots to charge the net.
As far as colleges go, as has been mentioned by many people, they vary widely. If I were you, I'd look into Tiffin. One of my friends went there and she told me they jumped from NAIA to D2 like a year or two ago. They seem kind of heavy on foreign flavor, so you'd have to be ready to compete. There are some D3 teams that you could start on now, and some like Denison or Kenyon where you'd need to develop to crack the starting roster.
