Some pretty good points are brought up here. I just looked at multiple Statesman Pens (since that was the example given) and on every one of them the spring came out with very little effort and none of the springs stretched or bent at all when removed. I didn't have to twist them out or anything, either- they just pulled straight out. I wonder if perhaps we had a tighter batch of springs at one point. As for including the springs in every pen, I will bring that up and see if that is an option. If it does happen, it will not be for a little while, however, since we have to order our pens months in advance. I'll also bring up the option of selling springs by themselves. If there is, then we'll certainly carry them. In the mean time, it might be a good idea to keep an extra kit or two at your shows for conversion ability. I realize that this isn't always possible but if you have a kit at home that you can bring, or even a spring from another kit, that would do the trick.
