Hello everyone, wondering if anyone has had a chance to hunt with the 505 or 705 and have a comparison in depth with the X-50 and 70.

I have been swinging the X-50 for a couple years, it has some really good points and works well, but I'm looking for more.

Money always comes into play, if I look at used what do you think will go deeper than the X-50 with out spending more than 700, or maybe the answer is the 705 new?
Any thoughts
