No experience with the Tank and have 2 games on my THE 9s. I came from SST5 Sports that started to fall apart after 6+ years.
I didn't want to spend the money on the THE 9s but after looking at everything available, I decided to go ahead and get them. Right out of the box they were very comfortable, no break in needed. The only "issue" is the fact that they only come with the soles/heels that are on the shoe and extra soles are $30 each while the 8s came with an assortment. The S7 sole that they come with are something I will never use and had to order a S8 and S10. I'll probably end up ordering a S9 and S11 at some point as well. Anything less than the S8 is far too tacky for me. I'm sure the S7 is fine for most, but the S8 used to be the standard, not sure why they went down to the S7.
The real test is league tonight. I do tend to drag my toe a bit and after reading some of the above comments, I hope the toe holds up better for me than other folks, otherwise I'm not going to be happy because of how expensive they were.
