I like the bigger corkies for chironomid and mayfly nymph fishing because you
can keep them in sight easier and you can use a small shot with them without
sinking the indicator on windy days. The shot keeps your chironomid vertical
more of the time when the wind is pushing your bobber around.

Anyhow, my casting with the 2 wt and bobber is soooo bad that I hesitate to
even call it casting. a 15-20 foot flip is maximum for me. Untangling snarls and
wind knots is a big part of the game on those windy days.

Micro, if you do get a 2 wt. full flex for chironomiding I highly recommend the
Orvis full flex Silver Label. It's very soft action and very forgiving, but you can
put a lot of pressure on large fish without worry of busting the high modulus
graphite. And do get a good 3 wt line for it. Those 2 wt lines just have no load
and if you ever try useing the rod without a bobber to cast you'll be disappointed
unless you got the added load factor of a 3 wt. The rod can easily handle it.
