Ok, I was just gonna say look at the guides or search out other threads, but I have to comment on this.
Tgod's is my personal favorite, Arach is hardly the only choice there is. Of course, I play HC were the safety like mods on Tgod's is more favored, but I can still hit 10k hammers at 125 FCR with it, and personally favor it over Arach.
Some even use Dungo's, although I have no idea why really, it has nice mods, but there are better ones out there, namely Tgod's and Arach.
Boots though, I prefer Waterwalk's. WW's give Dex for max block, better life, and max to FR. Treks, well, FHR is a plenty with a Spirit shield (use over HoZ IMO), base str can still be done without Treks, and the life boost is smaller (I forget if its even BO'able) and PR, yeah shouldn't need. WT's are for MFing. Hell, i'd use a good rare over Treks on a Hdin.
