Pure weight is very doable, I know because I have a pure luck fox so it would be essentially the same.
You have 2 options for training.
1) Equip a GS and GLS stack AP and melee everything. You may have to make up for the 1 in power by having 1 or 2 pieces of equipment as AC/DX whereever you are lacking.
2)Stack pure DA on everything and use shurikun skills + stone strike. Id probably more suggest this way just because I did it this way and know its not too hard. Plus this way enables you to make use of Fan of Knives which is a very handy mobbing skill.
hope I haven't missed anything.
