This is a completley unbiased opinion...
I've never run the Mtroniks, not since the days of the Little silver 2000 thingy.
I've only recently gone to the brushless set-up and I've found it an easy transition.
The Nosram Matrix speedo allows a seamless transistion beteween brushed/brushless. So you have the best of both ways covered whichever beomes the best option in the next few months/years. I'm not sure the IP6 allows this... please correct me if I'm wrong...

The Matrix also allows you to check temperature after the run. which is really useful to check whether or not the gearing/speedo set-up is right. Talking of set-up you can tune in the Nosram to just how you want your brushless to feel. The standard set-up is pretty close, there's more in there if you want it...

As I found at York by wheelying off the line in rounds 3&4... I've never done that before..........

Add to that the lifetime guarantee... Not that I've ever needed to use it in 5 years of running them. I still have my first dominator....

If you are gonna run brushless. Make sure you use silicone sealant to seal the wires into the connectors in the sensor lead.

But the choice is yours..As other people have said. If you're happy with what you have the service may not be important...

Also Nosram are World Champions in the very capable thumbs of Mr 'Dub C' Cragg.
