...I haven't heard of people having to make any mods to the Evo but I haven't really read much of this thread hope I don't have any problems, and how does removing the insulation help doesn't it help keep the heat in
Don't assume that you'll have any problem at all with the Evo. There are only a few of us that felt it "necessary" to make the mod. Try things out the way they were designed to be used first. And expect the best. Really.
There have been extensive discussions in this thread about the modifications. I suggest you first check out the tips for getting the most out of your Evo/Revo, rather than the mods you can make. I know the threads are long, but you do have a little time before your package arrives.
I just ordered a DART. I came into some PureGold this past week, and I've never done this kind of concentrate. So I've been skimming and re-reading the Revo thread.
Search is also your friend. If you're interested in the sleeve stuff, search this thread for posts by OF (who had a nice discussion about the effects of an insulating sleeve). Jam and I first started talking about alternative methods of using the Evo, such as putting the mouthpiece directly into the Evo core, quite a while ago; you could search on my posts or hers. Or search on the keyword "sleeve".
Or just read/skim through the whole thread before it gets to 100 pages.
