Whilst I appreciate that airspace is V busy,maybe it annoys us as pilots to be handed over close to level offs in climb or descent so a little forward thinking all round might stop these non standard calls-levelling off is not econmical and not particularly comfortable "down the back". Obviously most of the time it is neccesary but often can be avoided. Whilst on annoying can you TMA guys please sort out what speeds you want - 8 times out of 10 into LGW , London TMA say keep speed up then LGW say 210 Kts it is very "annoying"
