65kts for a 152? Bit fast I think. Tecnow it seems to me that you are flying at a 'add 5 kts for the wife and kids and then another 5 if there's an R in the month' type of place. Have a look at the POH (clues in the name...
) for the correct speeds and techniques. Having said that if your club has a particular policy then you need to abide by it.
