New rasp bars for a 2188 specialty rotor

I need some new rasp bars for my 2188 with the specialty rotor. I have mostly soybeans and milo, with a little bit of corn. I've heard alot of good things about the Gordon threshing and seperating bars and the Kile bars. I currently have bars that are from CaseIh and the back 1/3 are spike tooth bars, which I like for tough green stemmed soybeans. I'd like to go back with the spikes on the back but I didn't see any on the Gordon site but, I did see them on the Kile site. Which bars are the best Gordon or Kile? Could I put the 20 Gordon threshing bars on the front of my rotor and put the Kile spikes on the remainder, and it do a good job in my crops? TIA
