Poa trivialis, lets talk about it

Thanks to the forums on here my knowledge of maintaining a lawn and landscape has increased dramatically. One thing that has improved is identifying weeds and grassed. Unfortunately I have come to find out that I have both poa annua and trivialis.

I use to think the seeds coming up in late spring were good but it turns out that they were poa. I'm not sure when kbg goes to seed but I know that fescue need to get tall before doing so. Annua is difficult to deal with but it seems like trivialis takes the cake. I have heard that Velocity, Tenacity and even round up has failed when applying to it. Is this the kryptonite to great looking lawns? What can be done to stop this invader?
