I was reading a bunch of post about how much the original DID is better than the DUD. It just didn't make sense to me. With the DUD you can very easily adjust the air hole to your liking. You can sand down the top cap so that the air hole lines up with the wick when tightened. So why is the DID so much better? Yes, they use better material...but that just means it is built to last...not that it will perform better in the short run. The only difference is the wick hole. The DID has 2.8mm wick hole, while the DUD has a 2.5mm wick hole. Could this make such a big difference....in a word...yes.
I drilled the wick hole using a cheap 7/64 drill bit and a regular drill. Just do it using very little pressure and with a lot of patience...so you don't break the bit. You will end up with a 2.8mm hole. Once you get the hole bigger make a new wick as tick as possible and as solid as possible.
The advantages to a ticker wick hole/wick:
1) Much easier to wrap coils and getting the desired ohms.
2) Much easier to adjust the coils so that they are all glowing the same.
3) Better wicking...without needing to do the genesis tilt.
4) In General, just a much more stable coil that needs to be adjusted less frequently
5)Chances of getting hot spots diminish greatly
6) Can use use 30awg and 28awg more easily with greater effect.
The only draw back with a thicker wick is that it will act a bigger heat sink, so you will have to up the voltage. But overall in every other way it performs better.
