Asics Nimbus or Mizuno Wave Rider 17??

I have been recommended either by the shoe place who did running analysis and I can't decide!! I am apparently a neutral mid to forefoot striker and they also said I could consider the Brooks Free.

I have the Asics Trabuco but it's no good for road running and think it's added to my knee issues as has too much support. Always thought I was an over pronator but discovered yesterday after video analysis that I'm not!!

If it matters I'm 43 164cm and 46kg. Mostly do about 5km runs but want to do a half marathon in 2014 so need the right shoes!

Especially keen for opinions from people who've tried both.
