Michigan Apollo Prop

Thanks Guys for the input. I found a Mirage Plus 15 1/2 x 17 that will be here in the next couple of days. I am looking forward to seeing what type difference it will make. I won't run it for several more weeks, but will try to post the results. The Mirage Plus appears to be an older style without the vent holes, but I'm not sure that will make any difference in my case.
