There have some reports of teething problems with the new aristo system.
There has been an overheating episode on a SD-45, which should never draw over 3 amps. The TE decoder is rated for 5 amps with a 8 amp surge, and has a big heat sink.
The consisting capability is somewhat hampered by limited ability to match speeds for locos, there is a new firmware change that will let you offset one loco's speed plus or minus 25% over the range of speeds.
I don't think that is the right solution, but we will see.
Will keep you informed.
