actually, I just happen to have used the lsv the other day for the first time in a while. quite enjoyable, but it's still going to be mostly my Cloud backup. the cloud just tastes better, cooks more evenly and seems to be more efficient to me.
the Sub is a different, unique beast that I keep going back to. it has a very unique vape signature that really takes me back to college with its intense head highs.
I was feeling good back in the day with the Cloud and a HI as a backup. then the vvps for the HI became a real issue for me. I decided I needed a better cloud alternative when my beta cloud died, so I lucked into a good deal on the lsv. I love it and recommend it, but I still had to go get another cloud.
I think if you have glass and want to vape with it, the lsv is the best deal out there and will satisfy for years.
