why a custom built converter isn't for everyone....

I getcha. And remember, I have been in support of custom converters throughout this thread. Just stating that there are instances where it's more practical to not have a custom converter and I think I'm in that scenario. I know we disagree

The only time it would be practical to not have a custom convertor would be for walletary reasons.
In other words, financial reasons dictate a given build is OK to sacrifice performance.
Say you are buying shoes and wear an 11.5. Shoes only come in 11 and 12.Half sizes cost extra. Would you pay the extra for the extra comfort every day you have the shoes on?
