The reservoir I fish is without weeds or grass - just chunk rock , boulders , steep bluff walls and clear water (i.e. typical hyland reservoir ) . Most people throwing 'Traps and other Lipless Crankbaits are using FC or Co-Poly  in #14lb. to #17lb. because they are ripping through grass and weeds to get that reaction strike . For my conditions glancing off of rocks , digging along the bottom chunk rock with the nose , Yo-Yo'ing or a straight retrieve are what I can do with a lipless crank on my reservoir . To sum it up - I'm not ripping through grass so what line and #lb. strength is best for these conditions in a reservoir devoid of any vegitation ? Rod & reel choice  is no problem as I have enough combos for Braid + Leader , FC and Co-Poly to go and match with the best line for the conditions I outlined above . Thanks in advance ...

Since you're not ripping grass, I'd use 12-15 lb. fluoro on a 7 to 7'6" M or MH moderate rod.

I use 10-12# CXX in these conditions.

 

 

Thanks for the replies , both are good options but I am inclined to try the CXX in #10lb. on a 6:3:1 with mono backing on it to see how I like it - about 60 yrds. with KVD line conditioner should do the trick.  I would imagine the CXX down in #10 lb. should cast / handle well and be non-abrasive as a benefit around rocks .

10-12# Yo-Zuri Hybrid in as big of a spool as you can find.
