Fluke 6 inch gulp

[HighHook94]

So everybody has been hyping the gulp 6 inch grub for fluke. Seems like it's been putting a lot of keepers in other ppls boats. I fish in the ocean in 50-75 feet of water with bucktails and do okay. So I bought some grubs in nuclear chicken, white, pink, and glow. When I tried putting these on my bucktail, I was either getting shorts on my top hook, where I had a 5 inch white swimming mullet, or getting the tail of my 6 inch grub bitten off. I lost almost 10 grubs in one trip because of this. I know these 6 inch grubs catch fish, because I've seen ppl on other boats catching with these. I try to vary my jigging to see what works. Sometimes I try the John skinner type of fast jigging, and other times I'll try a slower bounce. I keep the bucktail around 6 inches above the bottom. And I know I'm fishing in productive areas. I just think it's my technique. Any help would be much appreciated. What do you guys do to get keeper fluke in the boat?
