At my local airfield where I did my training and had my 1st GA job there were two flight schools.
My flight school taught what I consider a nice circuit with good circuit spacing but the other flight school did circuits that were about 1.5 times wider than ours. This was a major hassel and slowed down the whole process greatly.
Once I got into one of the local charter companys the tower would often clear us in on the inside of the traffic in the downwind that were well wide. This was a great help from the tower because we did not have to slow a 206 down to fit in behind a 152 in the early and wide downwind positon.
