Get the MA3s. More expensive isn't necessarily stronger. I'm using a set as my touring/cyclocross wheelset and I have some rare anodized MA3s on my Steamroller. If you can, go with a 36 hole 3 cross wheel setup with DT Swiss double butted spokes (2/1.8/2). I weigh 185 and haven't had any problems with them after 5 years of use.
