I know many tests today that don't use matrices because people practice them.
And it's not like matrices are the only IQ test item type, almost no one practices the other item types.
So I wouldn't worry about practice effects.
They never last more than a month either way, most people forget, and if you don't forget, you're probably pretty smart in the first place.
