I got these awhile ago, and used them for my blm to 36 (so far) and my whm from 38-60 when I got AF Hands. The -enmity at that level makes a huge difference, and I've found people are wow'ed by them when they check me and want to know where I got them from. Likewise, for my BLM I used them from 25-36, and the -enmity made a big difference, especially if there was another blm in the party (he pulled hate constantly, while I almost never did).
2/2 on these, one pair for me and one pair for my friend who started levelling whm recently. Easy pop, moderately easy kill, but I would suggest a slightly higher level or a buddy or two with you for the kill, since he spams poisons and stuff like crazy.
