MS SQL query hint FAST for read XML

Question

I have followed code in my stored procedure:

    SELECT
        ID,
        <..some other columns>
    INTO #MyTable
    FROM OPENXML(@hXML, N'/Root//Element', 2)
    WITH (
        ID int,
        <..some other columns with types>)

When I checked execution plan I found that:

1. Estimated Cost 77,5%
2. Estimatd Rows 10 000
3. Estimated IO Cost 78,7%

My xml data usually contains not 2-5 items. When I user SQL hint FAST(10) then I can see estimation value near 0.

Should I use this hint? Does it help SQL Server perform query faster in some way?
