WAY back when I was working with Jason on this bait I wanted a smallmouth/walleye jig similar to the Mann's Stingray grub that would dart when fished on a darter head jig and would give more glide when fished on a 1/2 moon jig. I fish the upper Mississippi River and both fish like to sit in current edges and ambush prey.
So, I like to rig it tail up (like a minnow) for darting and tail flat for a glide/slower fall. Just depends on the day which they like best!
I have just about every mold Do-it sells and the Glider is still one of my "go to baits". Try hand pouring the belly in orange and injecting the rest of the bait in brown or green (depending on the color of your crawfish). For minnow baits, I like it in clear with rainbow glitter, watermelon green with red and black flake and plain ole silver. For minnows, try pouring a thin top in black and then inject the rest of the bait.
It's a great mold to improve your hand pouring skills!
I also like to use a laminate plate (or a homemade one out of thin gage aluminum) and make !/2 gliders in black. The really make a good leech bait!

And here is a post of some baits I made using a laminate plate and "T-shirt paint" from Walmart to make the eyes:
