Which is better for counter steer the tt01d or the sprint 2

counter steer kits easily available for TT01 - you have to modify sprint 2, but it is easily done too. CS sprint 2 requires good throttle control, especially on straight runs, the more counter steer the harder to control.

have anybody tried the active hobby counter steering kit for the tt01d

Its response time is good and its a lower percentage of counter steer. Works fine.
