I think I finally found a purpose for my dobyns colt 7ft light action spinning rod. I want to throw Sr-5 Sr-6 shad raps for late winter early spring bass.  This dobyns is the only spinning rod I have in the power range and soft enough tip ( it says it’s fast but, it’s slow for being fast)  I may or may not Have a new spinning rod by that time.  Incase I don’t, the colt may have to pull double duty for a while.  Being used as a ned rig, tube,  or other finesse rod.
 

At this moment it is spooled with 10lbs hi-vis yellow power pro braid. If I tied on a 8-10ft section of mono for a leader would that help with stopping the hi-vis from spooking the fish and act as a shock absorber? 2nd option I could go 8-10 lbs flouro main line than tie on a section of mono for a leader.  Again, using the mono  as a shock absorber for  bouncing off of rocks or fish. Is that enough mono to get the bait to back up after being stopped by a rock or other object it may run into? 3rd I could just junk the ned rig for a while as I can throw tubes on another spinning rod that is MH.  Which, I could just spool all mono. I took some nice fish on the ned rig at certain times last spring. 
 

I love throwing Crankbaits whenever I can.  However, I could not get the current cranks thAt I have to go untill the water was at least in the low 60s which, was mid June last year. That’s why I’m interested in shad raps.  I know people use braid for cranks but, for some reason my brain is saying don’t do it. 

Either will work fine as a leader. Mono is going to reduce how deep your bait runs more than fluorocarbon (mono floats).  Whether that is good or bad depends on the crank and the depth you want to fish it at.

 

If you're just worried about having a shock leader, use some copolymer. It has some of mono's stretch and some of flouro's stealth factor, plus it sinks.

I throw my shad raps on straight 8lb copolymer. I fish them in too cold of weather to consider using braid.

Co-polymer OR flouro may be the way to go.  than I can still fish the other stuff. I’ll just experiment on weather I need to run a mono leader or not.  Ive got pline flouro clear which is a mix between copolymer and flouro.
