Ok, for you guys that have ran shortys and brick packs indoors can you please share you experience with them. Did you like the way the buggy handled with one over the other and if so why? Also for those of you running shortys where do you like to place the battery. I noticed with the shortys that if you run the pack up front it leaves a lot of empty space at the back of the tray and seems like the front to rear weight balance would be thrown off. Thanks.
