I sometimes have problems with the factors #4 treble hooks getting tangled together when the lure hits the water. Its not till I retrieve the lure all the way back that I notice that there tangled. It does not change the vibration on retrieve when they are tangled however I am not sure if it changes the action. As a solution to this problem I changed out the hooks with #8's. I tried several different combos of hook sizes to get the biggest one's on I could. Two #8's did not tangle.

I just got done reading an artical on treble hook replacement and one thing that was stated is that even adjusting the treble one size can completely destroy the action to the point of it being actionless. I went down 2 sizes. Has anyone had action problems when increasing or decreasing their hook sizes on crankbaits. Any input would help. Thanks.

My Mad-N's do the same thing on occasion.  When casting, try not to put a lot of "snap" in the toss, and when the lure hits the water, immediately pull it just a bit with the rod tip.  I've found that doing these two things helps some.
