IMO, it depends on how you’re deploying them. If they’re in transports or hoofing it, they work best in minimum squads with picks to take advantage of as many hypermorphs as possible and access to all your assorted character buffs. If it’s a perfect ambush bomb they should be max size with as many hammers as you feel comfortable with. Abombs are going after armor hence the hammers, and will need the extra models to daisy chain back to any characters with them that might fail a charge.
