There are other trims you can get.....High peak, low peak, mid peak, dual peak and universal. There are problems with splicing at that range. A stinger a little too long causes all kinds of problems. The signature of the amp plays into it and the cable company knows that. I have had to get SA to write me something to prove my case before.
