Trips Open is one of the best formations in the game. Cluster and Bunch are great as well.
Empty Spread is a good addition if you're going to no huddle, otherwise I would just do 5 wide.
I'm curious how my roster will look next year. On defense, I'm losing five starters from my 4-3 and six from my 3-3/nickel.
On offense, I'm losing my 99 overall QB and running back (and maybe my 91 overall junior tailback too), and four of five linemen. I don't know if my new two-deep will be more equipped for no-huddle than my current one. I just know the overall dropoff will be huge.
I'm also losing my top tight end/h-back so I think I'm getting rid of split y-flex and y-offset. My new top two tight ends and fullbacks should finally all be in their 80s. I'm going to keep the ace big gun sets, hopefully. Twin TE slot power gave me a 79-yard touchdown run against #16 Bama. I'm returning three of my top four receivers and they'll all be mid to high 90s.
Since receivers are so easy to recruit, I'm going to refocus my recruiting away from tight ends again, if I've got enough depth there.

Looking at my current personnel and what I have incoming, I'll probably need to build something more power-personnel oriented, but the "Power Raid" first draft looks like this:
Pistol
Full House, Strong, H Twins, Strong Slot, Weak Slot, Wing Trips TE, Twin TE Slot, Slot, Wing Trips, Y-Trips
Gun
Split Offset, Split Y Offset, Twin TE Slot, Normal, Normal HB WK, Spread, Spread Flex Weak, Trey Open Offset, Trips, Trips HB WK, Trips Open, Wing Offset Weak, Wing Trips Offset Weak, Y-Trips, Y-Trips WK
