No hate at all that I see..............but down the road, maybe some toldjaso's.
Most of the people on here giving you some good advice have done / used what you are asking about more than once; you admit to not knowing & not having done it.
Your mind on the general configuration was made up before your 1st post & though I haven't been place really close attention to where you are now, but it looks like about all you've changed is going to a 16" barrel from the originally intended 18".
There are people / builders / manufacturers that specialize in different type of configurations, & your guy is obviously very good in his niche, but maybe not quite at the same level in this particular niche.
JMHO, YMMV
