Ok, thanks guys. I just wanted to check since some Dukes seem to not be recommended by others (#11 dbl longspring) for instance. I like the price as well.
I have to say, I've bought some Duke 1 1/2CS and #1 dbl jaw CS and they seem to be some pretty good traps. The springs on them are very strong. The only mods I've done to them is replace the chain with some good #2 machine chain and added some MB crunch proof swivels and also I replaced the pan bolts on the 1 1/2s. I may replace the pan bolts on the #1s as well.
