Can anyone tell me if there is a marked difference in noise reduction between the 1.6" diameter SUMO and to the 2" diameter RONIN. I have a SUMO on my Wildcat .25 MKI and it really takes the bark out! I was going to buy the RONIN, but it was sold out in .25, so I went with the SUMO. The more I think about it, the more I believe that the SUMO is the right choice for the WC .25. It looks organic and weighs less. I'm thinking the RONIN is a bit of overkill.
