Trick Drums P1V6P Drive Shaft

Got this a few days ago, service from Thomann excellent. I play on a Tama Iron Cobra double and although the drive shaft looked and felt pretty solid, thought to invest in the Trick drive shaft as soon as it became available, mainly to reduce any lag regarding the slave unit. So my thoughts so far are:
- Fits perfectly to my setup, no problems.
- It is heavy and sturdy, looks like a quality piece of equipment.
- First hour of playing felt different, made me doubt a little bit.
- As i continued practising for the next few days, i started noticing the pedals felt more responsive and light under the feet, slave pedal especially.
- Gives me the impression i have to tighten the springs a little bit.
- Needs little time to get used to.
All said, it is a good investment and so far delivers to an extent what it promises. Both pedals feel definitely more equal as far as action is concerned. Smooth is a word that fits for sure... Don't expect miracles though, you have to practise hard to achieve high speed, endurance and consistency.

Got it today and thought writing a review quickly.
I have a Pearl Eliminator 2002 C I bought new in 2008. 1 year ago I decided to push into metal music and started seriously pushing my double pedal game.
I am Impressed by the additional control I got on my left pedal, with the Trick shaft got much more feelings from the pedal. All of a sudden with this shaft you get more control, more response from the left pedal and beater. It is not as good as on the right pedal, but much closer than with the original pearl shaft.
Playing 16th RRLL on the double pedal, 2 days ago I was struggling keeping it for 8 bars straight at 155, now I got the same issue at 172!!! All of a sudden I am able to play much quicker. And I am confident with more work this shaft will help me having a cleaner sound, more definition, and even pushing further the speed.
Yes it is expensive for a shaft.... But i was considering changing my double pedal for a new model... Now this is over. I keep my good old Pearl Eliminator with Trick shaft, so good! So in the end... I save money ;)
Could I play as fast with the original shaft? I think so, but with significantly more work. This shaft is significantly better than the original one.
