Dear Sirs,
May anyone here on this Forum maybe already tested this CARBON based NEW SIRUI PH-20 GIMBAL HEAD vs Wimberley II?

Hello Dear Fellow Photographers here!
May I ask if anyone has already maybe tested this CARBON based NEW SIRUI PH-20 GIMBAL HEAD vs Wimberley II

I would appreciate any thoughts or experiences about this Sirui PH-20 - what I do not know is if the ball-bearings are made of high-end stainless steel parts? Maybe the Wimberley is better internally built? I could not find out all the specs yet.
Product Highlights:
Strong Carbon Fiber/Aluminum Gimbal Head
Supports Up to 40 lb, (20kg)
Weighs Only 2.4 lb
Reduced Vibrations Due to Carbon Fiber
Better Tolerance for Temperature Change
Arca-Compatible Quick Release System
Quick Release Plate Included
Tilts From +150 to -60 Degrees
Ideal for Using Long Telephoto Lenses
and of course one additional high light would maybe be the PRICE - in US = Price: $529.95 = (BH)

Thank you for any opinions about this relatively new item Sirui PH-20 Gimbal Head
All the Best!
