Gear Air Iop level 60-70

Royal Whirly Set Seems good. Royal Puddly seems like another viable option. The best is probably just going with stuff that gives you wisdom though, like the Infernal Set. Alternatively, if you could wait until the 70's you can grab the Lunar Set and compliment it with some of the Crobak stuff for things that don't overlap.

Depends on how fast you can level and if you've got 100+'s that might powerlevel you past some stuff.
