I've not held a TDZ b/c reel before but have seen pics & the bodies on both the Fuego & TDZ look very similar.  I know the inner workings & weight are very different but the bodies the same size?

The bodies are not similar, they are identical.

The TDZ, Fuego, TDX Air Metal and Zillion use the exact same body the only difference is the material used in the frame, the first three use magnesium, the other four use aluminum. BTW, many parts are interchangeable.

Thanks Raul!  But do the bodies of the Fuego & TDZ the same size?  I know the Fuego & Zillion are similar but the Zillion is just a bit bigger due to the bigger gear.

Identical size.
