need the 28/28 or will a 34/29 be enough?

... I keep grinding, need to manage my breathing
carefully for the last few hundred metres, but finally get there. I
can do it, but it seems not without a triple.
It depends on a lot of factors- the main one being how you want to
climb. If you want to be able to crawl up a long grade, perhaps with a
touring load on the bike, then you need low gears. If you are the kind
of rider who will always want to power up a grade at speed and never
carry a load then you'll never use them.
It's possible, I daresay, to get the low gear you need from a double-
the "MegaRange" style cassettes with a 34t big sprocket would give you
exactly the same gear ratio as your 28/28, though whether you would be
able to get a setup that shifted smoothly over the range you need I'm
not sure...
Still, if your current setup works for you... why change it?
