New PRO post compared to 2" carbon fiber post
Posted 29 November 2004 - 11:46 PM
I am putting together a new sled, and am looking for some input on post rigidity. PRO has a newer version of their 1 1/2" post. Does anybody listening have the new PRO post? What do you think about it?
I am trying to compare the PRO II post to XCS 2" carbon post. Not being in LA, it is difficult to get a hands on demo of both posts, so I would appreciate input from those who have flown either, or both posts.

My only beef with the pro is the fit between different posts, i have discovered a few thousanths of difference between the locking thread on the superpost and the standard post, ( build in different years ) which has resulted in some stripped thread issues, so I have been going to lengths to adjust the threaded insert in the lower post section to be a closer fit and have had a deeper locking collar fabricated to esure more thread engagement.....Again the problem of living away frm LA, the art may be affordable, but the shipping and or trip to the shop is a bit expensive....the lesson here is probably to buy your posts a t eh same time so George can check the fit before it leaves his shop.

I do alot of long lens work and I went to a solid post a few years ago to reduce vibration. I have been very happy with the rigidity of the new post. I feel almost no flex or vibration even in lowmode at 75mm with the post fully extended.
Also, I fly a lightweight II most of the time, but on my show we do a different flashback look for every episode so I've got different cameras on the rig all the time. No joke we are on episode 14 and we have used 12 film stocks and 3 video formats (tube Betacam, mini DV, Super VHS, 16 mm, 435, 8mm, 8mm extraction from 16mm...) I've had everything on my rig you can imagine in the last two years. My post and gimbal are all over the place. We will switch back and forth between formats twice a day. Reconfiguring is really quick, and so is going to lowmode.
I have been really happy with my post and my gimbal. I feel that they work together as part of a system that has been really well thought out. I agree that the gimbal is a deciding factor, but you have to look at both forward and backward compatability issues. I know that alot of people have frankenrigs but sometimes it's nice to avoid all those compatibility issues.
Just my two cents

Gregg is a serious wonk on rigidity. The thing I like about these that is not mentioned above is the locks on the ends. Each end of the post is locked to the top or bottom box by a bayonet mount similiar to the PL mount on film cameras but more beefy.
The inside of the mount has a rigid Amp multi pin connector so it is only necessary to plug the top and bottom into the connertor and spin the knurled knob tight to mount the post. This makes much quicker post changes, and allows breaking the kit down into a shorter smaller travel case. There is never any sticking or problem removing the post as on some units which lock onto tapered pins etc.
These posts are 2" dia carbon made by a special wrap that Gregg has had designed. They are amazingly rigid, and are a very exact fit under the gymbal with no change in diameter or egg shape in cross section, up and down the post, which I have had occur in aluminum posts after hard usage.
Bottom line posts from Pro, Xcs, MkV, and other quality manufacturers are of much better quality in terms of, materieal, design, features, toollessness, rigidity etc. than any of the rigs from only 10 years ago. Isn't competition wonderful!
