I pull and pin with the same. I use 22 if I am short of others, generally use 23 all the time, I've recently gone to 25 and it was slow but ok. Again I keep it simple. Just for easy going if I'm going to stab the rubber more then twice I will put on a virgin tip to pin with after loading with the other. After my old days with IV and IM I can handle about anything. However when I do ED the 22's and even the 23's get tough. ...crazy mike
