sweet choice in tacklemakers. I love mine. I think the pen tac size 3 should fit. You could always call them and ask. They've always been more than helpful to me. You might think about going with the size 3 blade, I use 4's and 4.5's for coho, chum and springs, 3's when they're spooky. As far as the body combo thing goes, I'd keep it simple and either use a pen tac body or use a painted bullet weight with a colored bead at the bottom. There used to be an outfit out there called mortac, but their website is down. They basically had the same stuff as pen tac, but with slight variations.
