Response Trigger

[partofme]

I;m thinking about getting one of these for my birthday but have some questions. First, Is it that if your not sweetspoting it, when you fire it it shots when you pull and when you release. I thought I read that somewhere. Also I;m comfortable taking the gun apart but was wondering how hard it is to install. Third and finally If I could be getting a new higher end gun that my 98c is it worth getting a response trigger? Or, should I jsut get a double trigger (which I am getting no matter what also) and deal with the fact that the tippy doesnt shot fast with out a rt?
Any response is good.
