I would skip on the pebble pusher, unless your willing to really look hard for a fruity pebble pheno by growing several out. I have 6 females right now, from 2 different packs and I only have one that barely had any sweetness to it. I am only around 40 days into flower though, so it may change down the road. Seems like the stardawg male dominates the pebbles in this cross...
If you were looking for a heavier indica I would probably go with TNT, Pioneer Kush, or one of the OG crosses. Someone not too long ago had several hibernate crosses they had made, f2s I think. Those would be nice as well.
Edit: I would also say that maybe you would get lucky and find a pebble pheno right off the bat. I remember when I grew Jelly Pie, every damn one of them had jelly terps, the grape pie really dominated the stardawg for once. Compared to everything else I have grown from GPS where the SD stud always dominates more so than not. Pioneer seems to be another one, where bubba has more domination as does OBS and Sundance Kid.
