Agree with the comments above. I always aim to have a booking with an airline that has at least one if not two flights after mine that would still get me onto the connection. If not then an alternative airline that flies to the same destination at a similar time.
You only need weather or a technical disruption and bang goes your connection. I prefer to have a longer layover, than take the risk of having to shell out a fortune for a replacement ticket. YMMV.
