After running a ported 7900, I picked up a stock one locally, and I was pretty disappointed. Compression was a little low, so I put a new ring in it and promptly sent it down the road... Don't know about the 7910, though.
So have you ran the 7900 in stock form and the 7910 in stock form, an how did they compare, that's all I was wondering
Since I've never ran a stock 7900 I was curious, I hear a lot of chatter, but it's usually people saying what they've heard or specs, I like to hear from folks who have had both or ran both side by side as that helps to separate the facts from the fiction that seems to be prevalent in the specs.
