Discussing your views on house sticks should be fine. I'm sure even offering them for sale would be fine if you're a contributing member of the forum, meaning you're posting on a variety of topics and don't spend all your time shilling for a certain brand.
As to my thoughts on house brands in general, I find that they're still the same as anything else at the B&M, you get what you pay for. And if your B&M is selling a cheap house cigar, they could probably be selling a cheap unbanded cigar for an even cheaper price.
