The mobility from TTC bases is the reason.

It allows you to change the arc on player movement (and it can compensate slightly for unbalanced figures and such.....so you can go straight without extensive tweaking....not the best solution, but it can help) and this can allow you to have a player spin in an area (zone defense on passing), or maybe create a looping blitzer or a running back for sweeps. Other than spinning in place or for guys who you want to change their angle of attack....all of these can be done with a rookie base though....but obviously, your spinning guy needs to be set to go straight at some time to make a tackle so a TTC is a must. TTC's can also allow your offensive linemen to shift their angle of attack....or allow a tackle to arc backwards and out to pick up blitzers from the outside. A fast TTC base on a running back can be very valuable. Your opponent won't be able to predict his arc of travel out of the backfield as easily as if he were on a rookie base.....the same being true for a blitzing linebacker....the offensive player can't be sure how sharp of a loop he is making if he is on a TTC.

TTC's typically could be made stronger than rookie bases.....till the Proline strong bases came along....and that was another advantage.

I have found that those Proline strength dials can be used in other shells to give you VERY strong TTC bases. The Proline TTC's as they come are not good.....the dials are loose and positioned too far back. You can do surgery to move the dial. An easy fix would be to cut out the post that holds the dial and then glue in (or just place) some friction bandage material to the shell....and then put the dial back in. The dial can then be moved forward and used....the friction tape will hold it where you want it. You might have to cut some of the shell opening to get the dial far enough forward.

Wait till you find the interesting things you can do with ITZ dials....true 360 degree movement....but best with balanced figures (unbalanced figures will not go exactly the direction of the dial, but you learn to use them!). The ITZ dials are not gonna' be very strong....but you can get speed out of them. I have seen them used on offensive lines with wide splits for running and passing. I did well using them for my offensive line before....for passing. Never quite got down the run game with them. Mklingbeil on this chat board is the guy to contact to buy ITZ dials.
