In my experience, Helix and Baccarat will never move. They're cheap, but not cheap enough for the guys that smoke the $30-40 bundles, and anyone that's buying because they actually like cigars will grab something like an Oliva G, Punch, or Sancho Panza at or near the same price point.
Don Diego babies sold at my old shop, but nothing else, for the same reasons listed above. H. Upmann didn't move worth a damn, either.
A couple of other things:
I see Cruzado up there, but not Illusione. You need to carry Illusione if you can. Our old shop didn't because of the scale of their production back then, and we suffered for it. It's a popular brand, not too pricey, and it'll move.
I'd also advise you to carry the DPG lines.
I'm not sure if you're already talking to reps about carrying these products, but if you haven't, you're probably not aware of how branding, etc., works in the business. If you're gonna carry Altadis and General products, they're gonna want you to carry more brands of their products than you'd like. If you're gonna carry Davidoff/Zino (and to a lesser extent Fuente and Ashton), each is likely going to want "preferred" placement in your shop such that they stand out - usually the stuff right in front of you when you open the door to the Humi. That can be a pain, because as a retailer, you want to give that spot to something that moves well and gives you a higher ROI.
If you're running a lounge, you want dark tile/wood floors, hopefully for obvious reasons. You'll want solid (preferably modular) lighting, and dark wall paint, as well.
Also, incentivize staying around. Good ventilation, keep coffee and water available, as well as menus for local restaurants that deliver. If there's a game on, leave the shop open til a half-hour after it's over. If you're gonna do a lounge, don't forget that you're providing a service as well as selling a product.
If a newly-released stick has a buzz about it, be the first shop in the area to get a box or two (even if you have to pay at or near retail), and send out an email announcement that you have it, and that it's a limited supply. It gets folks in the shop, and if it moves, you can develop the vendor relationship to make more money on the next box.
Humi floor space will be limited, and you need to think about what will sell best per square foot. That may mean carrying the full line of Tats and four sizes of Macanudo, or the opposite, and you just have to watch/listen to your patrons to get that ratio correct.
Good luck.
