Been there. Basically I was there, backed off, sold almost everything I had plus a humidor or two, and started over. I had sticks I would never smoke.
1. Don't jump on every perceived deal that comes along because somebody said its a great deal or a great smoke. You will end up buying crap you don't really like and it will just sit there. Everybodies taste is different and I guarantee you don't like some of the stuff that Bruce or Brian might like and vice versa.
2. If you have a local B&M, use them as your sampler. I go by mine and pick a different stick every time I'm in there and try it. If I don't like it I have only invested in one and don't have more that I won't smoke just taking up space. If you do find some you like then can look for the deals on them. Get to know the guy behind the counter and generally they make some pretty good recommendations. Me and Charlie at Burns ( my local B&M )have got to be good friends. His taste don't particularly agree with mine, but he knows what I like and will tell me stuff they have I haven't tried.
3. I'm a Broadleaf kinda guy so most, not all, broadleaf stuff I like. I'm also a medium to medium full strength guy a medium full body guy. There is a difference between strength and body and it makes a world of difference in the enjoyment of the smoke. Find out what you like in cigars and try sticks with that combo. I'm sure some will say I leave a lot on the table that I haven't tried because of my preference, but I generally enjoy what I smoke. I do have some favorite ISOM's that I keep on hand that are different then above.
Just a little advise from a recovering cigar whore. Hope this helps
