Clearly you have a drum to bang. Having converted a road frame to fixed with horizontal drop out, and a MTB with vertical dropouts to singlespeed, and owning both an SS/fixed MTB and track frame with trackends, I can say without a shadow of a doubt that trackends aren't merely aesthetically pleasing, they are the best for singlespeed. Maybe its a design thing, because its what they are designed for, rather than attempting to fit a round peg in a square hole.
And lets not get started on the spacing, 120mm rather than 130mm. It's a hell of a bugger to fit singlespeed rear hubs to the wider geared bikes, involving loads of spacers to get the chainline right and often meaning the rear tyre isn't dead centre. Yes you can convert a geared hub to SS, but that needs specialist tools to remove the cassette. Plus you get a dangling chain tensioner.
Build the K2 into a geared bike, and get a singlespeed frame to ride singlespeed. SS conversion are inelegant and tricky at best IMO
And my last word on the material: even low-grade tubing is better than alloy, again IMO
