Hopefully you guys will like this as much as I do.
The X-acto handles for x-acto blades work awesome. Obviously it is use to putting blades in so it works great for pics too. You will need to shorten your existing pic and remove some material from the top and bottom. Be sure to make it just smaller than the ID of the barrel so there is no wiggle room. After installing it, it has no play, real solid and has a great feel. As a test I picked up one of my more difficult locks and opened it twice within 30 seconds. Perhaps it was just lucks, but that thing really felt far better than the regular pic. Maybe there can be some further improvements...but the existing is pretty great.
