Most people using tube chute systems pack the spring type pilot in with the rest of the laundry. I've seen a few cars with seperate pilot system but don't see the point in complicating things any more than you have to.
I've built a couple of successful high speed systems this way in the past. The system on Al Teagues liner was idiot proof & faultless for 12 years & went beyond 400mph.
The pilots do get knocked around some but they last pretty good & they're not a lot of money to replace plus you need spares any way.
The chute testing that "cousin Paul" speeks of, was me testing my chutes with my blown Riviera at twice the speed limit. I packed them up in a cardboard box, sat them on my lap & when I got up to speed, tossed them out the window. It was interesting, got the results I needed & gave the local farmers something to talk about. My nabor came along for the ride on the second day, he still talks about it. I did repeated hits, increasing the speed each time. I wanted to know that they would fly straight, not spin or hunt.
When you deploy a low speed in front of a high speed, the high speed will collaps & hit the deck anyway plus you will tend to get burn marks on the low speed canopy from sliding down the high speed tow line.
Tossing out a high speed is a gentiler way to settle into the laundry without the big hit & then if you need it, use the low speed. I would expect this would be more critical on a bike liner.
