Experience with RSB Bushings?

I'm torn between RSB's from H&R and Neuspeed. With my new FSD's I'd probably run the H&R on stiff, or Neuspeed on soft or medium.  I've read every thread I can find comparing them.  A significant difference is the bushings - H&R claims maintenance-free, while Neuspeed needs periodic re-lube.  I'm interested in your real world experience with those bushings.
 
Are the H&R's truly maintenance free?  For those of you with that bar, do they actually remain quiet?
 
I've read somewhere about problems with the H&R bushings "tearing" and needing to be replaced. Anyone here with that experience?
 
For those of you with Neuspeed, what has been the time/mileage interval before the bushings start to make noise?
 
Has anyone added Zerk fittings to the Neuspeed bushing mounts to simplify the re-lube process?

i believe HKS setup has zerks on the bushings.  I've also heard the H&R bushings are prone to wearing/rubbing on the bar cause they use a different type of material.  they also tend to squeak [this is all from what i've heard. i too had the same questions.].  I came up on a used Nuespeed RSB and in all honesty, dont mind having to lube it once a year.  figure the car requires other maintenance as well so why not add just soemthing minor to it.

HKS is apparently only available as a front + rear set (for ~$400).  Both bars are 27mm diameter (tubular), compared with 22mm (solid) for H&R's and 25mm (tubular) for Neuspeed's.
 
I'm not interested in a front bar - don't need it for the way I drive, and don't want to go through the hassles of dropping the front sub-frame to install it.  And I haven't got any comparison with H&R or Neuspeed for effects of the HKS set on handling, while I'm pretty confident that either of those will have the desired effect.

I've had the Neuspeed RSB for well over a year and 25k+ miles and I only notice a squeak on speed bumps.   I guess that it's way over due for a lube, but that's not bad for time and distance?   Personally, with my Koni C/O's, the car runs perfectly well with the Neuspeed RSB set on its stiffest setting.   I just bought a new pair of shoes, so I'm anxious to wear off the slick coating and get going on some twisties to test it all out!
