I have been using the wa head for a few weeks now as I have been dabbing more than vaping. I was thinking of selling the sh as I just really like concentrates better. I put the sh on today to help me make up my mind and yep I’m keeping it!!! Both heads are different enough that it makes sense to get/keep both. The wide open airflow of the sh is just so awesome and dabbing off of SiC makes the wa well worth it.
