I did an ass-load of research and pulled the trigger on a set of Union Forces. I got them for $140 shipped. I'm slapping them on a NS Evo.
I was between the Targa, Force and Force SL. I think I made the right choice.
maybe if you were comparing 390's and Forces, but Targas do not come close. Buddy has 390's on his evo-r and loves it. More so than his SB with Forces
