I love the Indy combi bolts, they can use either allen or phillips tool, and the shank is solid like shorty's.
Not sure Indy makes them anymore, but i have a few sets in both 1" and 7/8"
If i'm running the 7/8" with cast plates, i use the thin shorty's nuts with them. Allows the bolt to come above the nylon of the nut a bit more.
Here's a shot of them, with a Shorty placed on top of one to compare head sizes.
(my OCD requires that the 'cross' on all bolt heads are all exactly aligned north/south to the nose/tail)
