Maybe on cross bows, But in general, I have no problem just adding to a thread. I do it a lot when trouble shooting something mechanical. Why re-invent the wheel.
I am not sure I agree people ignore them either. Lots don't pay attention to the dates and rattle on.
But I agree crossbows have come along way. But I also don't begrudge a guy who makes a quick posts, in a tiny thread like this. Half the thread is us talking about not posting in old threads.
