Basically anything 'Schumacher yellow' will work to a degree.
Minipins give the best ultimate grip but can make the car twitchy on steering. On my 2wd car indoors i like spikes rear with medium Schumy insert and either spikes front with cut medium insert or cut staggers and no insert. Gives a nice predictable car without the front feeling too lazy.
Really it depends on your skill level and car to what will work best for you
