Most of my setups are baitcasters with 15-20lb p-line fluoroclear on them. I'm using the Academy h2o xpress reel which seems to handle light to heavy lures. Could i get away with flukes on that type of setup or would i have to use the magnum flukes for the weight if using weightless? its in the 80s here in Georgia already so i know the bass are getting active. Whats some good colors to use for these?

I think you should get by with the Super Fluke without going to the magnum. That's what I always throw. Even easier on a double fluke rig. I like pearl and white ice colors. If not, put it on a spinning set up. I always neglect my spinning set ups but they are ideal in some popular lure techniques.

most of my rods are 6'6" med-heavy and my favorite is my 7' med-heavy rod since its light and i can throw anything a mile

If you are able to throw it then it should be fine. I throw weightless flukes on on a 51e but i've throw them on a 201e7 /w no issues either. a lot of throwing these will have to do with the correct rod as well. i throw mine on a 610mf and 12lb mono and can throw them quite a ways.

I use 6'6 medium heavy 12 pound fluro.. spinning reel

Last year I spent alot of time and money trying to configure a baitcasting setup to throw flukes. I found a 50e and loomis imx 783 do a great job at it but have since started throwing them predominantly on a spinning setup. Go figure.

I throw super flukes on an academy mettle, 7' Kistler rod, and 20# Invisx flouro. I use 20# to get those bass out of the grass. I hardly use spinning gear any more. This set up casts surprisingly good.

I throw super flukes with a 6'-6" rod with 15# mono.  I don't have any problems.
