I would be surprised if there is enough market for both.It's pretty cool that Mitas brought them back. Very few manufacturers are willing to do that. Sales will quickly show which version is most preferred. Perhaps there is market enough for both EO7 and EO7+ in both std and Dakar?
Now, about that other stuff going on in this thread. Don't Feed The Troll.
Having run the E07, E07 Dakar, E07+, I found that the 'failings' I found in both of the originals (not enough side traction when leaned way over, and not enough traction when straight up and down, which I define as "the damn TC comes on while I'm accelerating hard just going straight"), were not mitigated by the E07+. If the "+" version gripped so much more that I could run it without having to worry that during very hard riding I'd continually spin up the rear, then I think there would be market for it.
Based on my experience, I found that the so far the perfect tire for me on the Super T doesn't exist. I.E. a tire that grips the road like a AnakeeIII, but works on gravel roads and double tracks like a E07 / E07+ or Tractionator GPS.
I find the edge traction on the GPS to be similar to the E07+, so not significantly better.
For long road trips that have a large offroad component (600+ miles say) my first choice is probably still the Tractionator GPS. But not by much. With second choice being one of the original E07 configurations.
For long road trips that have significant corner-carving through some seriously twisty roads (like say OR 242), I'd still prefer the AnakeeIII. Or any other similar tire that has a significant road bias (maybe a Pilot Road 5?). I have an A3 in storage right now that I haven't put on yet as I was planning a trip south this year, but that may not happen given the state of the world.
Depending on how my summer riding shapes up, I may put another E07 on the bike if the Tractionator is sold out when I need to replace the current one.
Anyways, long response to your post, and I realize that I probably ride the bike differently than the majority of Super T riders as I ride the thing like a motard in the tight stuff, so as always take it for what it's worth (and my $0.02 is Canadian, so there's the exchange of course ).
Ride what you like, just make sure you enjoy the ride!
