...by increasing the sensitivity of the 330 I got clean catches...
Most factory conibear triggers, as you have obviously noticed, leave a lot to be desired. Paul Dobbins covered this in the TPC a while back. I have modified all my conibears (even my marten/mink traps) to fire with minimal trigger movement. This has made quite a difference in how fast otters are killed, especially with 280s. I just don't set 330s specifically for otter-I had a couple bad experiences, and decided it wasn't for me. If it works for you, go for it--I know of several trappers who set 330s for otter, I'm just not one of them. I just wanted to point out that 330s aren't my idea of a good otter trap.
How big are the otters there? Interior AK otters are quite small--maybe 20lb average, although I don't usually weight them. Otter in SE AK are at least half again as big, and some are just BIG--I know of several that stretched over 7' nose to tip of tail. I wonder if a 330 works better on larger otters, as I suspect yours are?
