Kisling,
If a D1 school is "very interested", I would not take that lightly.
I think this board sometimes creates the misconceptions that every ball player has dozens of offers to consider, the luxury of musing over those offers until they are all in and then make a decision.
That ain't the case in the vast majority of situations.
And, TPM, is right, those offers are generated, many times, as a result of the ball players efforts.
The D1 is showing relatively early interest,and with your indecision, could move on.
If there are uncertainities in your thoughts about the D1 school, maybe you should wait.
But, if the D1 "seems right", then it might be, and you should be prepared to move quickly.
If you snooze you might lose.
