Redline is on order and I will have it by this week. I can't wait to try it out, I been tore back and four on which one to keep. When I had my 8500 x50 I only use it when I travel the highway going to work so I don't really need the ix because that is good for the city. I will be use it in the city at first just to get use too but I will only still use it when I travel the highway. Taking a 1200 miles trip next month and I will be trying this out.
