I did more testing in the stick pack vs shorty realm.. Short pack is 100g lighter than the fantom 100c pack i was comparing against.

Shorty- black AE springs front and rear, the car worked well but was a little soft and slowish lap times. Same went for losi red front and white rear BB springs

Shorty-black rear and green front AE springs, Perfect! well, close to it. Ran the fastest practice laps of the night, had very little push and i had more control than ever. Might go down 1 step to 27.5 front oil and 25 rear oil tomorrow and test.

Stick pack-Green springs front and rear made the car push too much. Went to white front and green rear and improved. Car still felt heavy but lap times were improved from the other stick pack test runs

In the end i stuck with the shorty for another day, green front and black rear springs, AE BB shocks, 32.5/27.5 oil, 1.6 pistons, 24mm ride height, battery had only 1 pad in front, big foam block in back. It feels very responsive and the lap times showed it, can't wait to race tomorrow!
