I HIGHLY reccomned getting a race gun. I have had a race on my cocker for about three months now, and not one single problem. Their customer service is unbelievable and they are coming out with their own line of electro cockers. They also have an anti chop eye coming out in about a month or so. The uprising doesn't have an anti chop eye. The race gun all you need to change is your grip and three way(four way). The uprising you only change your grip, but you must send it in to be installed. The race gun you can do your self. The race costs about $550-650? The uprising costs about a hundred bucks less, but it's your money. Go to Race Guns web site at: www.racegun.dk.
You can get all of your questions answered on their forum. Hope this helps.
