hey perch slayer i always fish with a bunch of tip upa and i use a 4" to a 8" smelt or anchovie about 3/4 to a 1 foot of the bottoma nd i try to find a sand flat that emptys in to deeper water. if u can find a corner of a lake or a point is great. right now im fishing a corner that is a sand flat that slowly emptys into deeper water. its not a very steep drop off though. i try to set my tip up to cover all the angles on or 2 along the way to deaper water and 2 out to the sides this covers fish comin and goin into deeper water.
hope this helps.
