base width for contact

Hi there, I've been fitted with contacts with base curves of 8.4, 8.5
and 8.6 at various time. I now only wear contacts for a few hours at
a time (eg going out, or swimming or other athletic sort of stuff).
That's due to dry eyes with long wear and no longer being vain enough
to bother. I've found contacts on line for a cheap rate with choice
of BC of 8.3 or 8.7, both just outside my usual range. Is it better
to go slightly smaller or slightly wider? The contacts in q are
Acuvue 2.

thanks

the nominal bc is not really so critical when comparing brands,
company a's 8.4 is not necessarily the same as company b's 8.4
stick to what you are fitted in by a professional.
