4-tooth drop (e.g. 52-48) / 3-tooth drop (e.g. 14-16-19-22-26)

This thread inspired me to go home and build a new freewheel. My two prerequisites were that I would use a 42 small chainring on my Campagnolo Nuovo Record) and a 34 large cog on a Suntour Perfect Ultra spaced six speed freewheel body.
Here's the end result---
A 14-17-20-24-28-34 freewheel. Should I make any adjustments?
Now, how should I gear the crankset? 42-46, 42-47, or 42-49 (the chainrings in my spares), or something else?
Your wise "vintage half-step" gearing advice is appreciated!
