Replying to What Should I Buy?!

Ok everyone on here is opinionated, so give them to me (your opinions...) ARWs or Missdemeanors?? I can't decide which ones to get...

I'm 5'7, 125-130 lbs, I am currently on a 155 TM's, I like them but they are kinda short so I want something a bit longer. The ARWs only come in 160 and 170, and I think the 160's are maybe to short(??) and 170s too long(??) (maybe I'm just a pussy??) And the MD's come in a 164 which I think would work well, but I honestly have no idea...so please help. ALSO is $485 CDN w/ bindings a good deal for the MDs?
