APM offers two fork mounts.  One is considerably more expensive than the other.  With my sights set on ordering a 120/90 SD soon; which fork mount would be the better choice?

Thank you in advance for any thoughts or answers.

.."The APM fork mount is the result of user feed back. (Was not the user feedback here to come up with various contraptions like a door stopper inserts??)The optimum, smooth manual tracking, coupled with nearly (?) no vibrations and at the same time a high load capacity are unsurpassed."

.."This fork-mount is suitable for our 100mm and 120 mm binoculars, and the 28x110 binocular."

Well, that's interesting... It seems that the more expensive mount was designed specifically for the 150mm binoculars, but can also be used with the 100 and 120mm. The other one was designed for the 100 and 120mm models.

 

The more expensive mount is heavier, as expected: 6kg vs. 4.6kg, designed to handle a heavier load (26kg vs. 12kg). Other than the difference in weight, the principle and design seems similar.

 

I think that for your 120mm binoculars the least expensive will work fine. If you don't mind spending more money, don't mind having a heavier setup, and possibly thinking of upgrading to the 150mm model, then you could consider the more expensive one.

For my APM 100SD FCD100 binoculars, I purchased this mount https://www.teleskop...--Teleobjektive -Teleskope.html and very happy with it.
As you can see, it is quite inexpensive compared to the APM mount.
As far as I understand, the 120mm binocular has the same body width as my 100mm binocular.
