I'm sorry, I am being very anal this morning (its early) and have to correct your spelling... it is "Turm" Zerker, turm as in turmoil.
Ok, now that we got that out of my system. A Turm Zerker is ALOT of work, and very expensive to make. If you have the time and money though, I would definitely reccomend it. It would be a fun project, and Turm Zerks are one of the most highly sought after characters as they are alot of fun to PK on.
Just make sure that you FULLY quest your defence, don't train any defence at all until you have done all the necessary quests that will give you defence exp, or you will ruin your account. The link below is a guide here on Sythe that lists all the quests you will need to complete in order to make a perfect Zerk:
