I used a K1 4” in my 408 and have a BPE 4.125 in my 434, both checked out great and have held up well. I don’t ever see me buying anything from Hughes again.
can i ask ? What happened with Hughes that you'll never buy from them again ? they always treated me well never a problem good communication I found them easy to work with , gave prompt refunds if there was a problem. Maybe I was lucky ??
