No rule against expressing an opinion.
However,, how many posters here have put on in their hands yet? None have said so,, and by looking at the picture & description are passing judgement,, BOTH good and bad. I CHOOSE to wait to see one before I make my PERSONAL decision on liking it or not. If I went solely on pictures or other people's word,, there are a few guns in my collection I wouldn't own right now.
And for the record,, my personal opinion on what I see in the picture & description,, I wouldn't exactly get excited over one. I'll wait until I see one to pass judgement. Yet,, I CAN see the potential for many folks to actually get excited & want one.
