Tinks 69 is an estrous scent. Non-estrous does will be repelled by it. If a buck is following a doe and the doe runs away from your Tinks 69, the buck will follow the live doe. It should however work on a lone buck unless it's way too early in the season. Try using both an estrous scent and a dominant buck scent. This may bring in the big boys but the little guys might be driven away.
