If you plan on still duning your machine,i would get shear inframes.they are durable and perform well,but they have the shittiest chrome on the market. I had the out of frame shears with the silencers and they bounced around alot and I got rid of them and bought the RDZ out of frames non silenced.they are one out each side and they are loud as fuck,but perform just as good as my oof shears. jeff
