Just some initial impressions --
For context, I've only had my Ego-T for a bit over a week. It arrived as I was running out of juice -- so the LR Type A's that it came with have seen a fair amount of dark juice -- since I had just about 2 tanks worth of BWB Malty left (which is NOT dark), and have been vaping almost exclusively BWB Waffle since that ran out (which is quite dark). (Assume everyone has seen the comments about dark juice and the Ego-T attys.)
Made a trade for some lighter juice which arrived today, along with my LR Type B atty and tanks from cignot.
So I've got low experience with both.
The A's definitely started to get a harder draw quickly with the dark juice, there is no doubt about it. I've cleaned both of the ones that came with my kit twice already, and I don't think it's *quite* restored them to "like new". (I used one of the pretty basic hot water methods I saw in a video, nothing more extreme than that.)
The Type B has only had about 1/2 tank through it since I got it earlier today. It is bigger, but the size difference is due to girth, not length. AFAICT there is NO difference in length in a completely assembled unit. However, my Ego-T is now the same diameter for its entire length, including the atomizer. The tip on the tank tapers more abruptly, and this combined with the diameter seems to be where it gets the bigger volume.
My first impression of the Type-A was that it made lots more vapor than my KR808D1 horizontal cartos with the same juice -- and it did, but it seemed like that declined quickly as I used it more, just like a carto would. So after a few days I was getting more than a used carto, but probably less than a brand new one. As noted, I understand that the dark juice was likely to have been a significant factor there.
The Type-B arrived along with another package which contained some juices I had traded for. These are various fruit flavors and all are NOT dark.
All the juices are 80% PG, 20% VG, which is far, far less VG than the Malty I finished up on my Type A's, and also even less than the 30% VG in the Waffle I've been vaping in them. So the expectation would be that these juices would tend to make less vapor than the Malty was making in a brand new Type A if everything else was equal. Not so. I'm AMAZED at the vapor I'm getting from the 80/20 juice in the brand new Type B -- it's more than I was getting from the Malty (which is 80% VG) in the Type A.
I'm amazed at how light the draw is, but without comparing back to back with a new Type A I'm not sure if the difference is huge or just noticeable.
The real test will be when BWB gets some Malty in stock again -- I'm very familiar with how Malty vapes in a pretty good 808 setup, and fairly so with how it vaped in the Type A's when they were new. So that will enable a more apples-to-apples comparison. The juices I received with the Type B today are all things I've never tried before.
