I like letting go completely, but I have tricks in case I need to use them in dire scenarios. For instance my friend henri was thought looping quite badly a couple of weeks ago. I was able to get him on a bike and moving and calmed him down almost immediately due to his large muscle memory in that regard. Role play control is just a fancy way of getting someone into a familiar role while they are in an unfamiliar mental state to help them relax and let go. I have trip sat many times sober and many times while tripping on low doses and each time I have found it easier to help people with overly intense experiences using that technique. The last time I completely let go on a trip I was on ~5g of mushies and I thought I was having a heart attack at one point but it was quite enlightening and I experienced ego-loss like never before. I can definitely support the mindset of ensuring a good set in setting I just also accept the occasional need for dealing with people tripping too hard to be quiet.
