Just 3 would I use in that scenario: A generally affordable set ---------- 24mm 50mm 100mm
But if one must have 4 ... A nice set ---------- 31mm 43mm 77mm 150mm I don't go as far as recommending 200mm because of size. The set of 3 is lighter & easier to carry. -- -- Collin Brendemuehl KC8TKA "The problems are so over-rated." -- Petula Clark --
