Dynasty,
I don't have any of the quality penlights that you are looking at, so I can't comment on any of them; however I do have, or at least HAD three penlights, and none of them were particularly ideal for shirt pocket carry. They were all too heavy (unless maybe I was wearing a particularly sturdy shirt, like a mechanic's shirt) also they were too long for shirt pocket carry. They'd be fine for inside jacket pocket carry, or pants pocket carry.
I'd like to suggest that you look at a stainless or Ti single cell AAA light. They are shorter, and lighter and will fit into more shirt pockets without pulling on them too much. Ti and Stainless will remain clean looking, and some are more classy looking than others.
Personally, I like the smooth elegant look of the cnqualitygoods CQG S1 CNQ002102 if you get one, be sure to get the $1.50 clip that must be purchased separately. Also, the switch has not been the most reliable, but customer service has been acceptable. I have found that I use this light more often than I thought that I would have. Unfortunately it seems that it is not currently available in NW.
There are other Stainless AAA lights available, but most, if not all have some kind of knurling. There are some AAA/10440 stainless or Ti lights available you might want to look at them.
Just a thought
Have a great day.
