mikey is right, spend the money on training, thats the only way you are going to get anywhere, BUT if you must have 2 markers then the ego7 is the way to go, if you can afford, one of the lightest markers out, nice and efficient, feels really nice in the hand... well its pretty much the best marker on the market at the mo imo, many people will agree with me yet many will also disagree, in the end its up to you.
much easier just to spend the money on training
