For my first mold, I would recommend the essential series senko... As far as the sluggos, I would look at the 3 inch crappie carrot or the 3.5 inch skinny carrot... As for the slim senko, look at the 5 inch skinny carrot or either the 4.5 or six inch finesse worm.... The nice thing about the carrot and finesse worm molds is that they offer a laminate plate which allows you to easily make a laminate without the use of one of those expensive dual injectors
Before you order your molds, you need to order a sample pack of baits from do-it... They allow you to pick 5 baits that you are interested in and are only $5(shipping included) This will allow you to actually see the bait up close and personal, so you get exactly what fits your fishing needs...
