As andyp says, you really just need to work out what works for you in any event you take part in. Other factors will come into play - how strong you are feeling on the day, how strong the wind is, whether or not you are behind a derny!...etc etc. If you find that 48/15 is "a little small", try 49/15 and go from there.
