I run LW + Engi. The goal for cats is to max your agi, and (before the new wrist enchants) 120 agi >>>>>> anything at the time. The new addition of agi to gloves from engi is amazing! I do agree that JC is probably a very solid choice - I gem resil over agi (because of the huge target on my forehead), but would prefer to have more tools like burst agi over extra resil. Profs are pretty balanced atm, but a recent cat guide on the wow forum site said LW was top, followed closely by all other non-gathering profs other than tailoring.
