TTPro .61 on a Tiger 60

Looks like it will take from a 11-6 to a 12-8 prop.

Iran 2 tanks with a 11-6 prop but the guys thought it looked small so They loaned me a 12-6 for the maiden flight.
The plane has more than enough speed for me now with the 12-6. I'm more interested in slowing it down for landing.. Would a different prop help with that?

Also I bought a 12-6 and a 12-7 prop and a reamer. Is ther anything I should know before reaming?
Previously Ihad used a tapered reamer and I see this new reamer is stepped. Is it safe to assume these steps are standard sizes and one of the steps will fit my motor?
With the tapered reamer I could taper from each side until it fit. Now Ionly have the choices of the steps...

thanks
