im playing around with the polini variator right now. she's just slipping with the red spring at 12g, put the stock spring back in and she rips pretty well.
jumped up to 18g and she's doing much better but only topping out low 50's - whereas with the tjt / treats plate at 6g (i think? maybe 12... but i think im at 6g) and stock springs she RIPS and hits 60. I feel like i can crack the red spring (running treats endurnce belt btw, stock hobbit springs and the straight cut trans gears) with increasing the weights in the polini variator... might jump up to 22g in the polini or so and see what happens w/red spring
i like the polini variator better but it's a lot harder to tune. it's smaller then the tjt and with my tjt on the crank it has some wobble...which will cause issues down the road, where-as the polini spins straight :)
will report back
