I have the 1.75 Crappie Carrot and love it - it was THE best bait I was tossing in the fall for larger fish. Clear with silver and a little blue flake was on fire.
Check out the Pin tail Shad mold from Lurecraft - that is a catcher extraordinaire. If I only had one mold that would be the one for me. It catches fish in every month and the mold pours easy-peasy. I have the Jacobs paddle tail mold and it is another easy one to shoot and is a fish catcher.
I have used MF plastic for years and like it a lot - same as Snake River above. Lurecraft makes some good stuff too. Both offer great customer service.
My best advise is to heat your plastic moderately - scorched plastic is not what you want. Slow and steady wins the race so resist the urge to over -nuke it -- frequent stirring for me please.
Good luck!
