Differences/benefits of the "hard-anodized PTFE-Coated" shocks vs the standard ones?

[Trailwalker]

I'm looking to order some TRX-4 shocks (not for my TRX-4 but for an SCX10 ) and I noticed that Traxxas offers both the 8260 ("Silver aluminum") shocks and the 8260X, which are Hard-Anodized PTFE-Coated.

What are the benefits of the latter? They are only bout $15 (Canadian) difference per pair.

The biggest difference you'd notice is the PTFE coated ones are going to be a bit smoother feeling, but as far as actual performance goes I'm not sure you'd really notice a difference on a TRX-4. On a Slash or something of that kind you might. I wouldn't worry about it unless you like the peace of mind.
