EZ Lift torsion bars

Mostly depends on the tow vehicle.
One key thing is to buy a WD hitch that suits your trailer tongue weight-  IOW do not buy 1000 lb bars for a 400 lb tongue weight rpod. 
Dealers like to push the one size, usually with 1000 lb rated bars and they are too stiff for a lighter trailer.   

I've used EZ Lift hitches for about 25 years. They are an old school hitch that do a good job, but can be a little frustrating until you get used to them. Proper set up is crucial and sometimes a PITA--correct height, correct number of washers for proper ball tilt, number of links to drop for proper weight transfer, remembering to disable sway control when backing so you don't sheer it off the hitch or tongue. And, as Budward said, for a Pod, the heavier bars will be very difficult to adjust correctly-550, maybe 750 pounders would be as big as I would go. One nice thing is that EZ Lifts don't squeak and groan like some of the hi tech new stuff.

Any WDH, EZ Lift included, will help lessen the hobby horsing you may incur while towing. But I've said it before, "Sway control is not sway cure". Load correctly, set up your hitch well, choose a good trailer- tow rig combo, or pay the price with white knuckles and a greater chance of disaster. Yes, I'm preaching. Inattention cost me $40,000 or so in tow rig-trailer damage.

P/S Bottoming out has never been a problem. I've scraped a couple times. If you don't have risers on the pod and your tow rig sits low also, then---

Did they happen to mention when it is too much?   I've heard of people bending their trailers a-frame with too stout of bars, generally happens in a deep dip.
Mine is also 600/6000 for the rpod, I also have a 1000/10000 for another trailer.
