Short story.

Bought new cassette, wanted 11-32T but didn't change option from 11-28T, D'oh.

Do I;

Harden up and deal with 28?
Return it for 11-32T?

Pros as I see it;

Harden upingness is increased.

Cons as I see it;

Found spread between 11-32T was too close anyway and nearly always flick 2 sometimes 3 cogs at a time up or down. 11-28T is going to be even closer in ratios. (Haven't checked what cogs/teeth are different)
