I bought this head and the legs separately and I believe the head has a 150mm bottom, and the legs have a 100 bowl. I am able to sit the head on the legs and tighten it onto the bowl and it seems pretty solid. Is this a no no? At some point, several years ago, I bought a Manfrotto adapter but seem to have lost it. I have actually never used this, and have no idea what the dials do and am wondering if anyone has one of these and can explain what the ideals do, how to adjust the drag (I assume that's what they so), etc. I am thinking about selling this but do't want to mislead anyone so wanted to understand its operation who I cold test and at the very least give a buyer an idea as to whether the thing works well or not. Also wondering if anyone can advise on a fair price for both or as separate items?
