I have not tried the cell pal, but was intrigued by it, I decided it wasnt for me, when I heard you had to have your pants loose, and have to have both hands to draw from, and especially return to the holster. If you wear tucked shirts all the time, I have some ideas for you, I have been carrying non stop 365 days a year 24/7 for the past year and shoot IDPA with my carry rig and do it well, what I have learned is that iwb will be your fastest to draw from, I carry a glock 19 with a galco king tuck, which has been sufficiently comfortable for daily carry, I have also tried carrying that in business attire and figured out that will not work, it was too bulky. Start with the gun, I would look for a single stack 9 or what ever is thinnest first, secondly try to keep the handle short so it hugs your body, then carry it in a crossbreed super tuck, or mini tuck, depending on the gun size, stay away from that versa carry, it's not tuck able and also it does not cover the trigger fully, which is a no no. If you find that iwb won't work, I would go with pocket carry, because it is the most concealable in theory, also you can have your hand on your gun without anyone else's knowledge, with the downside of slowed draw speed and limited access while seated, which ever of the two you choose, I imagine it will have a limited capacity, so i would really recommend the tuck able ammo carrier also from crossbreed. Now whatever works for you, what I did to make sure I was prepared and like my carry set up was order the holster and buy the matching training gun(blue gun) and wear it around for a little. If you don't like it you can often return the holster and blue guns are cheap. For maximum comfort while iwb wear an under shirt if it gets sticky.
