I think the answer should be obvious. Double the weight capacity, Iso-Elastic arm (it's not just a marketing term!), proper stage (no silly sliding to fiddle with), and a high-brightness monitor. It's a top-notch system, but it does cost significantly more.
The X10 is more comparible to the Steadicam Pilot, which is still years ahead in sled design (I've never used an X10 arm, so I don't know how it stacks up to the Pilot arm, but I've heard it's not favorable).
Ive got a Flyer and its fantastic. The design and manufacture quality is incredible, I have no doubt that my flyer will still be working as flawlessly as it does now in 30 years time (although i hope to have a bigger rig in 30 years).
The Flyer is an official weight limit of about 7kg but I have sucessfully flown 9kg on it, and I have even flown a RedOne digital cinema camera on my Flyer. I also have a job with the F900, and it can handle fine with these sized cameras.
The flyer is a fantastic rig, I have no regrets, even though You can buy a similar rig that is cheaper and/or has a higher capacity, I wouldnt swap my Flyer for anything in the same kind of price range.
I hope to upgrade to a Clipper3 soon.
The Flyer LE is better than the normal flyer anyway
If you live in the UK (anywhere near London) then you can come to my place and play with my Flyer.
Comparison between steadicam and other products always seem biased from the steadicam owners perspective. You always hear how great or superior the steadicam is to anything else.
Well, it true...
If you are a steadicam operator (someone who has had the proper training) it much easier to spot the differences. Its hard to buy a car when you dont know how to drive, you would not understand the nuances involved in operating the vehicle.
Can the X-10 produce the same images as a steadicam? Of course, except you will be sweating bullets to get at least 1 take to work. With client breathing down your neck, loosing light, going into OT, it just gets harder.
Steadicam has created units that are flexible and provide options to users which do not exist in other brands. For example:
-If I am doing a concert and I am front stage,6 feet below the talent I can tilt the head of the steadicam to point up and still preserve dynamic balance. Thats quarter the work I would need to do if I had to tilt the entire sled for 2 hours.
-If I need to pan up I just lift the arm and it stays there while remaining iso-elastic (ride function). I dont have to fight the springs.
-If I need to go from a straight shot to running down the stairs and need to tilt down, I hit a pre programmed button and the motorized stage dips the weight forward changing the angle of the unit.
The List goes on and on. As time passes all these functions are being made available from high end units to cheaper ones. Hoarp wants to get a clipper 3 because he's been bitten by the operating bug and can tell the difference. We'll see him with a clipper 3,4 and 5 when it comes out.
Here is my opinion and I tell this to all my students:
Before you buy a steadicam, take classes. Learn how to use it so you can compare the units and pick what works for you.
