Finally! after 2 days of waiting, my RRS shipment arrived.
I bought the following:
TVC-45 tripod
4 series leveling base with hook
long lever clamp for quick change of heads
BH-55 ball head with dovetail adapter
Additional dovetail adapter for my existing video head
XL RRS tripod bag
I’ll be comparing the TVC-45 to my Manfrotto 055CXPro4 legs.
There are a ton of reviews online about the BH-55 so I’ll spare you with rehashing information, and instead I’ll try to focus on the TVC-45. (Aside from the fact that I’m completely impressed with the machining and quality and smoothness of the BH-55. ) The biggest thing for me after using 3 other ball heads is the layout/orientation of the locking knob. FINALLY, a locking knob for the left hand while i hold the camera with my right hand.
QUALITY
I know there are many reviews online, but I’m completely impressed (again) with the quality of pretty much everything. Anything you can touch is either machines aluminum, or carbon fiber or rubber. (aside from the flat mounting platform, which is a hard plastic). The way the legs feel when they’re pushed to the closed (center) position like when collapsing is very sturdy and precise. The leg locks near the apex push out with ease. They remind me of an older sliding phone. it feels like you’re pushing it over a very shallow, smooth hump, which then keeps it extended, but just barely. The locks automatically collapse when you push the legs outward to their furthest setting. all of the bubble levels that aren’t part of an articulating section all match (precision), and the twist locks (my first twist locks) are very nice.
SIZE
To put it bluntly, it’s huge. Granted the largest tripod i’ve ever owned previously is a Manfrotto 055CXPro4, or the pro3 aluminum variety. The platform of the 45 is far larger than the base of the manfrotto or the base of the BH-55, accommodating a 100mm bowl. The metal protrusions that accept the legs extend quite a ways beyond the apex ring, making for an almost 7 inch diameter. Despite the massive size difference, the whole package weighs only slightly more than the 055CXPro4 and 054 Mag Ball Head. By slightly, i mean subjectively picking both up. I haven’t checked actual weights.
Also, the second thinnest leg section of the 45 is about the same thickness as the THICKEST section of the Manfrotto.
HEIGHT
With the bottom 2 leg sections extended, it’s already about 4 inches taller than the Manfrotto with legs fully extended.
I’m 5’10” and with the lower two sections extended, my camera is at eye level, and that leaves 2 entire sections to go. Fully extended, the camera is far over my head. about 7.5 feet in the air.
LEVELING BASE
The 4 series leveling base is equally large. There is a hook at the bottom of the post to allow hanging pretty much anything you want with a carabiner. The action is smooth. No wobbling. doesn't take much force to lock or unlock.
My only gripe about the whole system is that there's no way to get the large clamp on the leveling base to line up perfectly, as you just screw it on.
Enough with the words, on to the pictures:
1. Both tripods with no leg sections extended.

2. 5D3 mounted to the RSS rig.
