I would STRONGLY recommend you re-consider the lowering blocks if you'll be doing much rough stuff. As advised by another inmate, the lowering blocks extend the fulcrum and increase leverage on the foot peg mount. I'm awaiting my third foot mount, and will be removing the lowering blocks.
On the street, they're likely just fine and they do help the knees in terms of ergos, but sheesh - really poor design from Kawi.
I have the Touratech pegs, and I would not buy them again for 2 reasons; (1) they aren't 'sharp' at the teeth (which also prevents the boots from being eaten up), and (2) they have a round profile - convex, I believe - that along with the absence of sharpness in the teeth creates a slip hazard under power in rougher terrain.
I took the rubber inserts off the TT pegs when installed, so no comment on a street user perspective looking for vibration reduction. I can say that with the rubber insert, they're pretty tall.
PivotPegz makes a versys-specific peg, but out of Australia and spendy - cool idea though. Most of the aftermarket has a different diameter pin, so you'll have to drill the peg to accommodate a typically larger bolt at the mount.
I've purchased the $10 ebay pegs, they're well made though a bit small for me. I may mount them up for a ride this weekend, might be happy with them. Great value, and many inmates really enjoy them.
Some would argue Fastway makes the best peg. IMS makes an 'adventure +' peg that is really cool, not for the V specifically, but drillable. They, unfortunately, have the same un-sharp teeth, so you'd need to take a file to a few of them.
The pic is the first broken peg mount, a real 'oh $hite!' moment for sure. I'm 165 + gear, and was carrying about 25# of luggage and stuff, so not overloaded at all. I did hit a rain rut at about 40, but there's evidence of prior cracking so it's just not meant to take a beating with the lowering block.
Just my experience. Good luck!
