For me, the biggest help in building a sequence is the timing. I have used other sequences as a baseline for making it my own. I don't necessarily use the specific effects, but the placement of the effects or the timing of those are helpful for a place to add in my own effects that show off my props. Many times the sequence would not fit my layout very well, but the musical timing gives me a big leg up. Jon and I have done this between ourselves several times. Our layouts are quite a bit different, but we can take each others sequences and use the placement to create our own versions pretty quickly. Many times I can look at videos of other sequences and take the timing cues from that and place my own effects. I know everyone is different in how they work, but that may be another option is to export effect timing and use that as a baseline to work from.
