4r70 and IRS with 4.10s, but I would also like to entertain the idea of swapping to a solid in the near future.

Might as well see how far the IRS will take you, if your willing to destroy it. Then replace with SRA. Or sell a good IRS for funds towards a SRA. There are people getting into the 10's with the IRS. Your call...

^ IRS has gone 9.20s this year! That's the new record. But racing with the IRS is always a gamble.

I was just wondering about this last night.

I'm with Posi on thinking the IRS could stand a real fighting chance as long as you never leave off the brake.
