Sounds to me like its not rolled tight enough, and possibly not oxidized enough. Once I finish my rolling, oxidation is about a 15 min process for me of heat, quench, heat, quench in tap water (the extra mineralization found in tap water helps the 'crust' build up on the wick) -- and there is almost no flexibility to my wicks after that -- they're extremely rigid.
Also, specifically for my fake DID and my AGA-T+, I had success by using a square that was roughly 60mm x 40mm, and rolling it as tight as possible, followed by trimming off JUST enough to get it to fit in the wicking hole... basically peel back the top layer of the SS and trim off a little strip til it fit perfectly. Then, I trimmed to length, pulled it out and began oxidation work. That way I knew once I got it seasoned and running right, it was going to work without frustrations.
Absolutely pick up a dripping RA -- if you think its gonna be more up your boat, they can be had for 10-15 bucks at many places -- but keep your Genesis-style! You WILL eventually get it. My fake DID got messed with for about 3 weeks, getting less than stellar results til I got tired of dealing with it. I then set it aside for 5 months -- and only just reapproached them about 2 months ago. Once I tried again, I instantly saw exactly what problems I was having where, and was able to solve them in about an hour. Now, recoiling my genny's takes me about 5 mins max and they deliver expected results, every time.
Edit: Not sure if it helps -- but you might be able to get an idea of the kind of density I find works with SS #400 from this pic of my AGA-T+:
