Nice pics and I agree that the Chopped-Off Limb is a prime mog target (my din has it as well, it being over-sized means it's normal size on a Belf).
Due to bagspace constraints I've mostly just mogged eye-sore items like the Scales of Akumai, Kazcugo's (spelling) Gift, Corpserompers, and esp. the Boots of the Clown from Hillsbrad.
Would be great if they'd allowed to mog the skins from White Items (ie White skin to Uncommon+, perhaps by destroying the White Item in the process) as there is a real shortage of low-level shoulder models & colors (Scouting spaulders - think black Serpent's Shoulders - would look great on many toons, as would a lot of the other White shoulder models).
