Elias, from what I hear you shouldn't be disappointed with the RSST. I personally disliked the marketing strategy but if you refrain from making nonsense comparisons, you may very well find that its a respectable atty all on its own, within the range of the more affordable ones.
That being said, if you can put your hand on a DID, it will probably be a life changer. And even if its counter intuitive, you will save a lot of money in the end. I often had the feeling the attys I bought besides the DID were kind of superfluous... Another thing, it looks like the fc2000 is being made with the DID in mind. The DID is a no brainer.
Now about the 20mm vs the 22mm. So true! There is one mod I know of that fits the DID like it was made for it and its the Precise Plus.
"I like things to have smooth lines" too and I was rather furious that MMvapors didn't come up with a similar mod (20mm) in continuation of the DID.
Curiously it seems I was the only one affected by it!
Yeah the RSST looks promising indeed, I personally dont go for product because of the marketing...
With my RC helicopters there is the cheap quality, good quality and originals, the cheap are so you can practice on, drill holes through and basically throw away when your done, the good quality ones are the step below the originals if you cant afford the originals you get those.
From personal experience it's best to spend the money on the originals and be done, no more issues with this doesnt fit or that is loose or this leaks etc.... and in 90% of the cases it works out cheaper going straight for the best rather than working with the others.
I know I am preaching to the converted, and really repeating much of what most say, but being an engineer I do like to tinker to the extreme, trying this, trying that and seeing why certain things are better than others like center posts, earth screws, wicks, coils batteries the list goes on... I will end up with something at the top end, just like with my RC helicopters I have 2 originals of the models I like and one is 100% standard as the manufacturer intended and the other is with the mods I found worked best. in some cases there is almost nothing to mod which is similar to these DID's and Zens etc.
As far as the precise plus its a 14 size battery 450 long and I prefer the shorter mods, I will never take with me to work or going out a mod and atty that ends up being that long I cant fit it into my pocket, so hence why I prefer the 18350 size mods, but they are all 22mm and not many atty's are 22mm in size...
Ive noticed a pattern when I drink and that is I write too much and most likely boring or annoying the readers, so apologies for that but it's Saturday night here and like a concerned father I am waiting for my daughter to turn up and as time ticks on I am drinking more to reduce the stress...
