Flow 556ti

Should I pick it up or wait for something better? My ffl offered me one today for a considerable discount. I currently have a flow 762 and most of my rifles have huxwrx muzzle devices. I had been holding off for a spiritus... but may jump on the 555ti. Looking for opinions? This will basically live on my 11.5 SD.

Before everyone starts talking about flow supressors and such I have 3 other non flow cans (all nearly top ranking in their categories on pew science). All more or less in dedicated applications and I prefer shooting the 762ti over the others.

TLDR should I jump on a good deal for a 556ti or wait until something new and shiny comes out for a dedicated 556 can?
