I have been using a Bogen 3021 for years and have found it to be more than adequate. I have used it with both a monorail (Cambo 45NX) and a field camera (Tachihara 4x5). I use it with a 3030 head which is on the small side but has worked great for me. I use the same tripod and head with my 4x5 and my medium format camera.
