Should you lap Heatpipe Direct Touch Coolers (HDT)?

I have a lapped X6800 and a fresh Xigmatek HDT S1283 in front of me. My CPU is flat as hell and my HS isn't. Placing a credit card flat against the base of the HS and in front of a lamp, I can see the littlest amounts of light peering through. I really want to lap it but don't want to end up like this guy http://www.evga.com/forums/tm....m=365730&mpage=1&key=& .

Would you ever consider lapping a Heatpipe Direct Touch (HDT) heatsink?
 
SHOULD you? Really not worth it. I doubt the gains would be huge, if noticeable at all.
CAN you? Carefully, apparently.
 
I was tempted to register on EVGA's forum just to add to that thread (but didn't, they want too much personal data, not worth it for a casual post); the OP trashed his Vendetta lapping the heat pipes, then announced his intention to return it to Newegg! If he lapped an IHS to the point he destroyed a CPU, you think he'd try to RMA that, too?

edit: FWIW, I have a Kingwin RVT12025 (Xigmatek rebranded) that I haven't lapped, though I lapped my E6300 IHS and the Sunbeam Silent Whisper the Kingwin replaced.
 
I wouldn't lap the heat pipes. A tip for the direct contact heatsinks is to fill all the gaps around the heat pipes with TIM as well as the gaps between the HS and CPU - this is one case where more TIM is better than less as TIM is most certainly a better heat conductor than dead air pockets...
