I run a flow in both my mod and stock short course with a reedy 17.5 and a reedy 8.5. I like them a lot but the others you mentioned are good quality too. The rules for stock are 17.5 and esc running in blinky mode (no boost or esc timing). As for tires on the indoor track, I like jconcepts pressure points or bar codes, proline ions, square fuzzies or suburbs....all in either soft or super soft depending on the temperature....hope you can make it down to a race at rchr soon. Just check the race calendar on rchr.biz for details..
