I say use the fins, but don't bother your lanemates. If they don't have fins, do stroke drills while
they are kicking, ie do some right arm only laps, some left arm only laps, some catch-up and glide
laps, basically kicking without a kickboard but using your arms a bit, at least to stay on the
interval the others are using.

I agree, and the drills I suggested will do that. But this is not to minimize the value of kicking
with a board. There are, however, a few people like you and me who will *never* improve as kickers
without fins.

That *is* true in my case. I swim faster with a pull-buoy than without and the difference in speed
is significant.
