1. shimano core50mg/ cumara 7ft medium- my senko setup. what is the best line for this combo?

2. quantum kvd tour(7.3:1 ratio)/gloomis frog rod(7'1'' heavy-fast)- frog setup

Is this a decent frog setup?

3. quantum kvd tour(6.6:1 ratio )/ quantum kvd tour 7ft medium heavy cranking rod. Is this the right combo for lipless?

Which Cumara?  There are a whole lot of them that could conceivably fall under what you just listed.  For instance, I have the CUC72M, the CUCX72M, the CUC72MH, as well as the CUCX72MH.  My preference for weightless soft plastics is the CUC72MH, it performs better on weight less plastics, and the tip loads better than on the CUCX72MH.

What line>  I'm more and more pleased with the Stren Fluorocast as I use it more.  Prior to that, I was 100% Seaguar.

#2: Yes, it's a fine frog rod. 

#3:  I prefer the 7'4" M for lipless baits.

Hmm...

It ain't that complicated.

Spinning tackle: #6 Yo-Zuri Hybrid  or Hybrid Ultra Soft

Baitcasting gear: Hybrid #12
