I currently use the Ti Maxmadco and the Tactile Turns Shaker Ti. I've also been using the Machines Era Pocket Pen in SS (not pictured) since it takes the Uniball Signo 207/307...which I like. The Max is a little thin, but fits well in a short, jacket, or pants pocket. The Tactile Turn Shaker in Ti is nice, too. I like the Fellhoelter, but can be a bit large (in length) depending on where I'm at. Jim at Maxmadco, Will at Tactile Turn, and Chadwick at BigIDesign all provide excellent customer service. I haven't had any communication with Fellhoelter or Machine Era. I think any of these pens are great...but if you're into pens...none will be your last...;-) Sorry about that...and enjoy!!!
