Yeah, the Castle is a nice vape too. The GR1 has a much lower profile, but if you don't mind the bigger top cap, the Castle really is a great buy at that price. I only used my Castle for about two days before moving on to the Recurve, but I ordered another one at the price to help fill out an order to get free shipping. I know I will use the Castle from just a short introduction to it.
I typically only keep two RDAs built and in rotation at a time, currently it's the Nudge 22 and Recurve. If I kept a bunch of them ready to go like a lot of you folks do, the Castle would be in the rotation too.
Maybe I need to build a bunch of stuff this weekend so all I have to do is wick it an go. I just don't like leaving a bunch of stuff wicked up if I'm not going to be using it regularly for a few days. It's just me I guess, lol
As far as the dilemma between the RSQ and the Pulse, that's a tough one.
I really love the RSQ, it's just a nice small squonk. And agree, I usually build a single coiler at 0.5ohm or above and do pretty well at lower wattages on a single 18650. I still have to swap cells at least once before the day is over though.
My Pulse should be here today if the USPS stays on track. I'm thinking it's probably a faster chipset, and although I lose the size factor of the RSQ, I like resin panels, and the 20700 option is nice to me. Even though most of my builds will still be single coils in the 0.5-0.7ohm range, on a Sanyo 20700B, running 25w, that's some killer battery life. Easily all day on one cell and I chain vape since I work from home.
They both have trade offs. The Pulse will be my main mod for a while. Once the newness wears off, the RSQ and Cut will be back in the rotation. The RSQ is a great mod for out and about carry due to the size.
