Most people wouldn't notice just like they probably dont notice the core in the 912 and both 811s are the same. It is interesting how they pick and choose which int diff to use from different weights when naming a ball versus say using the int diff of the 15lb ball everytime. It seems a strange naming route to take knowing when you buy the 508a ball you actually get a 5 series ball with .07 int diff and Angular ball reaction.

Overseas equipment obviously doesn't apply to their naming change since the made a long production run of the Phoenix Series along with a 4 series and several other releases to include the Kinetic Energy re-release. Since there isn't many Track guys on here we may never know what makes the 811a an SE and the 811c/t not. Maybe they will start making 3, 5, 7, and 9 series SE as well.

Hey guys, I haven't been on in a while. With work and building a house, the forums have been a back burner. Ok the reason the 6 and 8 series were special editions, was because they were going to be a line that came out maybe once every two years. Hence you haven't seen a 6 series in two years. When the 8 series came out I assume they felt that it was only going to be one ball just like the 6 series was. The 811A was a pretty big hit for Track. So with the success of the turbo legion core, track decided to put the strongest cover they could and create a 9 series homerun ball. Yes the ball would have been the 911T. The problem was they didn't want to upset anyone with 9/11 significance. This is why you have the 912T name. Now this next part is just pure speculation. Many people have assumptions about the Track 9 series line. Which most is true. I felt as though Track's best 9 series was the 920A and 916AT. The rest were just ok. Well the 912T definitely was the best. It hooked as much as you wanted a ball to hook. Now comes the 811c/t. I am assuming the reason they came out with the 811c/t was because the 8 series just sells better than the 9 series. So instead of coming out with the 912C/T, they decided to stamp it 811C/T. This in turn probably creates more sale for the company. It isn't a special edition because it is the second ball in that line within a year. I am sure if they come out with a 6 series this year it will be a special edition. I hope this answers you question. If you have any other questions feel free to ask. I will try to answer them as best as possible.

Yep sure does. 811C/T gives you more length than the 912T with a touch more recovery. Can't go wrong with the 912T, 811C/T and 811A. All are damn good.

Thanks Curt. Had a good idea on the 607 and why it was a special edition, and assumed the same for the 811. When the second 8 series came out and noticed it wasn't, it seemed a bit strange. As in maybe they will continue it as a regular line.
