Tech Trifecta

I'm declaring my trifecta for the Tech Stakes. This will not be a sprint but staying power will be rewarded. Fundamentally all three are sound and will not breakdown in the longer term. Ignore current form the odds will shorten as the techs come back into favour. For an outsider at longer odds I will put in PWR. Anyone prepared to put other techs for the Spring Carnival. I currently hold KAZ, SMX and TNE. I also hold LOK but worried about it breaking down - may have dickie knees.
