I have owned all three. Currently a Longbow owner 8 years, will never sell. Tom was based on mach1 co- designed by Venom team and is a 20+ ftlb rifle. Longbow is shortened action christened baby Tom at the factory and better suited to 12 but still has the envious pedigree and epic build/fit/finish of Tom and with a better barrel. Although it hasn't much in common I like to think of Longbow as Omega mkII with improved stock and trigger. Best 12 ftlb BB ever made and the prettiest by far.
