Were i fish the water isnt clear i use straight braid all the time and have no problem with bites.   But should i use a drop shot rig with straight braid

Normally, I believe that if it's not broke, there's no reason to fix it, however, I only consider fishing straight braid in heavy grass and that's not always a gauruntee.  With drop shots and finesse baits in general, I'm trying to become more patient and better at dead sticking, so this is a technique I'm working to get much better at myself.  To me, fishing finesse means lower visibility and softer, more flexible line to allow a more natural action.   I use about 4' of 7lb FC Sniper leader above the hook 80-90% of the time (unless I'm planning on fishing near nasty cover, in which case I may use 8lb Hybrid instead).  The way I see it, I'm very confident in my double uni and the lower visibility of the floro/copolymer can't possibly hurt.
