I use the Easton SE16. Great stick. Light as a feather, feels nice and solid. I think they discontinued this model so you can get them nice and cheap while they last. I paid $125 for mine in December or November.
The SE16 is a phenomenal stick but it is very different from the X60. The SE16 does not have the contoured shaft that the X60 does and has a more traditional feel. The SE16 is also less snappy than the X60 and is better for loading up on your shots. The SE16 is also no longer in consumer production so it can be hard to find the flex and blade pattern you want, the EQ50 is the replacement.
