1.3 display ideas

[Shotfire1]

I started getting into 1.3 display fireworks last year, thank you Dave. And I'm using 3-4 and 5 inch shells this year from kellners and lynch imports. My question is what cakes and mortars are in everyone's opinion here the best from these two dealers. I am not going to be able to make it to either demo. Any opinion will be helpfully. And any info on how you set a show up would be great.
