I am looking for a matched pair ballpoint and mechanical pencil primarily though a rollerball would be nice as well if it matches the pen and pencil as a complete set. I prefer silver bodies and a 0.7mm lead with a tip that retracts for shirt pocket carry.
I have read a lot of 'mixed' reviews of the newer rOtring products and must confess I really like the true old German brass 600 series. Today, the Hex-O-Matic seem to be a worthy competitor to the older rOtrings though, I really don't have any experience with them or the newer rOtring offerings other than some very casual use and handling at various places.
I want a hex body so it won't roll around too much and prefer reasonable knurling where I grip it. I also like a little weight overall with the balance being slightly biased towards my fingers, though still fairly neutral overall.
I have a couple Caran D'Ache 849 pens but, the refills are a little hard to find for me and while a really good pen, they are a bit too small and slick for my everyday use pen. I am sure there are some other pens and pencils out there that are worth serious consideration but, I really don't know where to start beyond the Retro 51 and rOtring options. Ideally, I would like to stay in the $30 each range but, I have some flexibility for the pen and pencil if something presents itself that is truly worthy of a higher price, though I'm not interested in 'bling' for blings sake.
