To be honest I wasn't aware there was a difference between the two,( Fenn and Springer). I did get some of these cheap, shiny, shite quality traps stuck in with the order (didn't have the springer stamp), which I'm returning. The Springer traps look fairly quality though, but I'll go and have a look at the Fenn for comparrisons sake.
I haven't made much of an effort to hide the rafts, I'm not sure how you would hide the monstrosity, so intereference is a real concern.
Ditch_Shitter : How big is the 'base' of the raft your planning on using?
