I picked up a RSST from the local B&M, and to be honest I'm not that impressed with it. Spent yesterday learning to wrap the coils. Using 32 ga Kanthal with (I think) 6 wraps came out to 1.9 ohms. Redid it this morning with 3 wraps of 32 and got it down to 1.3 ohms. Better, but the flavor of my black honey tobacco is no where near as good as on either my tank/carto, or my Aspire BDC Viva. Using wire rope with some ekowool on top under the coils. It hits kind of airy as I think the previous owner drilled the air hole out to 1/16+ I guess. Its a very airy hit. Am glad the guys let me have it for 20 bucks, so I dont feel I wasted too much cash on it. Bought it mainly to mess around with actually. Maybe its because I'm using it on an SVD at around 13 watts right now, but have tried different watts and voltages. I've got a mech mod coming so maybe it do better with it. Oh well.
Few things, these are just my observations from using the RSST for a few days... The draw isn't like a BCC or BDC clearo. It is more airy but I think that's how it's supposed to be, takes some getting used to. I find that when I vape my Aspires now it feels like I'm trying to suck a tennis ball through a garden hose. So maybe clearos just have a very tight draw?
The top cap on the RSST is big so it seems like a lot of people use air reducers in them. I wet a cotton ball and stuck in the top in the shape of a horse shoe. Flavor is much better that way although I didn't mind the flavor before.
Aside from oxidizing the wicks are you burning them with juice a few times before use?
I've made about 4 different coils for my RSST, 2 normal and 2 micro so far and in any configuration it blows my clearos away. Especially the vapor production and nicotine.
