Has anyone used the Dunlop Sport overgrip in tennis?

It's the only overgrip I've ever used and I want to know how it compares to others. Is it especially...comfortable? effective? water resistant? etc.|||Never heard of it. These are the Dunlop overgrips available from TW -%26gt; http://www.tennis-warehouse.com/accessor鈥?/a> I personally use Prince DuraTac. I like the tacky feel. My hand doesn't sweat much that need the absorbent overgrip :)
