My son has the Rival RS2V gloves in 14 oz. I like them a lot although I have only done a couple of rounds on the bag just to try them. Very good for all round training. Very good knuckle, wrist and thumb protection. Shouldn't be too harsh on your sparring partners either.
Not sure about the durability has he's only had them a month or so, but the quality seems very good for the money.
I would recommend these.
