I have done hundreds of katies, a lot under 20 mins.... I would Never want all trollers. I would rather have all fenders than all trollers. I want 2 trollers, 4 fenders, and 2 blasters. A Kin fender with FS at 32 is awesome, dark fender, rad, cold..... and then the 2 trollers /rad.... and blasters.
I have done a couple with you, and they were ok. Both were around 30 mins. But anymore I am used to them being 25 or less. Add more defenders and you'll be knocking off a couple mins. that's just my opinion.
