FlyinTiger, looks like you did your homework. I have been trying to decide whether to order the LX or the Extra Special now for about 2 weeks. My girlfriend says I am wishy washy. I am leaning towards the LX but it kinda concerns me what it says about having to use a little bit of mixing on it. I have a 9C but have never had any good experienced pilots really show me what to do. I have a NIB Taurus TS52 engine sitting here just begging to be installed on a plane. I think I will go ahead and order the LX when I get up on 2/15. Just get it done with. Quit thinking about it. Spend that money.
