Weight of Horseman 6x12 and Linhof Techno Rollex?

Anyone know the respective weights of these two backs?

Linhof does not specify the weight of the TechnRollex. Only the negative size, 56x120mm.

Pending someone being able to dredge up some literature or some backs to weigh, my recollection is that the Horseman is something like 19 or 20 ounces, the Techno Rollex much more, maybe as much as 32 oz.

Thanks Oren - that's very helpful.

OK, B&H is showing the weight of the Horseman as 590g.
