Many thanks to all who have posted, interesting that for something so critical as aproach we have such a wide range of opinions on this. I have had airfields ask me to do OHJ (Cambridge unexpectedly did on my QXC

) and there are airfields that state OHJ as part of the joining instructions - but then didn't seem fussed when we joined crosswind (I wasn't PIC), which is why I asked the question - I would be interested in an ATC answer to get their view as I think all the answers here are from pilots.
I will keep the excellent piece of advice to hand though - that there is no rush to get into the cct
Now can I have some decent weather at the weekend to fly????
