Max,
Jason is right the D12 is good in 19 turn. I only got to run my car once last year before they closed the track, but it was pretty good.
As for t-bar vs. link cars, that debate will probably go on forever. Each person has their favorite. The t-bar car is good on smooth tracks but is more likely to break. Link cars are better on bumpy tracks and very durable(no t-bar to break). Both cars are winners.
Link cars 1-2-3 1/12th mod at Cleveland
T-bar won snowbirds and nats on carpet
both cars in A-main at the worlds.
So, yeah the D12 will work for what you need.
