Howdy,johnapu.
I agree with woodsmoker, about the high temps on a kettle finishing the skin on a yardbird.
Have done that for many years.
If you are a big skin eater, than a kettle or even gas grill will be handy.
A Smokin'Tex will not address this issue,anyway.
Many competition cookteams will carry a kettle,if they don't have a hot spot in their offset, to finish the skin on chicken just before turn in.
Sometimes I do this ,to keep in practice.
Mostly our group peels the skin anyway,so I don't bother.
I'm not sure who the "many feel that hung ribs are superior" would be.
We are at cookoffs any weekend that we can reach one and I can't tell you the last time I saw someone hang a slab.
I know some vendors, that have uprights, hang the slabs because they are cooking and selling high volume.
Other than that,I think I hear woodburner sayin' "its the cook that knows his cooker that produces the quality product".
He has perfected cookin' on his kettles, over the years, and produces quality without a lot of effort.
I know lots of folks that will never get a good slab off a kettle.
I don't think I hear him sayin' he'd go out back next Feb. and throw some bronto spares on that kettle,when he has his Cookshack settin' there.
Just my $0.02
