The first time computers and slot clubs made comps available to a low roller such as myself, I read a few words of wisdom. If the desire for a comp causes you to change your play, they have won. I remember one time banging away at a video poker machine at Hooter's for about an hour to get a t-shirt, a free drink, and twenty dollars free play. I did not need a t-shirt, any CW would have given me a free drink, and I already played the twenty dollars. For Diamond players, just scale up.
