Sorry I missed this one,
Ultimately testing would be the best way to determine your favorite choice.
I have found, Labbing a M+ on a hull like yours will give the best top end and all around performance including carrying good loads.
Right out of the box a Laser 2 will have the best hole shot and the Tempest will fight it fo rthe best top end speed with normal loads. The Mirage Plus Labbed will win in the end and won't hurt your drive.
We 21 Tempest Plus and Mirage Plus wheels for testing. I'll have to check on the Laser 2.
