General No-Till

I have recently purchased a case ih 955 12\23 planter and I need to put row cleaners on every row for planting beans after corn.  I am concerned about blockage from the amount of residue that will be moved in the close quarters of the row units.  I have found a special unit by yetter that is made for 15" rows and would like any input from someone who may have used these row cleaners.  Speed will definetly have a huge impact on how well any row cleaner will work and the units are so close to each other on this particular planter that I'm concerned that I will have to run very slow for the row cleaners to work properly.  Thanks in advance for any insight.   Greg
