Best method to open table for Add.new

Wath is the best method to open access table with jet 4.0 to use Add.new ?
Actually i use:

Set RST = New ADODB.Recordset
RST.Open "table1", CONN, adOpenDynamic, adLockOptimistic

my conn:

Code:
Public Sub APRI_CONNESSIONE()

On Error GoTo Err_SomeName

Dim PC_OPERANTE As String

PC_OPERANTE = Environ$("COMPUTERNAME")

Set CONN = New ADODB.Connection
With CONN
.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\temp\dbtest.mdb;Persist Security Info=False"
.CommandTimeout = 1000
.ConnectionTimeout = 1000 'Tempo in mS prima che il tentativo di connessione vada in TimeOut
.CursorLocation = adUseClient
.Open
End With

Exit_SomeName:
Exit Sub

Err_SomeName:
MsgBox Err.Number & Err.Description
Resume Exit_SomeName

End Sub

please explain me also about cursor type, i think is important to leran speed up conn and open recordset...
