When to acquire a glider over the course of paragliding lessons?
Thinking hypothetically, person A is taking a paragliding course over the course of a year in three stages. The first two are about mastering ground handling, taking off, basic landing, different approaches, and landing near a target. The last stage requires 10 hours of flight in total, staying in the air with wind bouncing up from a cliff, big ears, and top landing.
Person B is an accredited instructor giving classes to person A. Person B proposed that person A acquire material for the third stage. Person B also suggested that it would be harder to teach person A with a glider unknown to person B. Person B suggested one specific glider that he knows very well and considers the best for beginners (Gin Atlas 2).
I see the advantage that person A would both learn the skills and to handle the glider; I see the disadvantage if person A mishandles the material and wrecks a new glider instead of a used one.
What is a good time for person A to acquire material? And what trade-offs should they consider when deciding on which glider to acquire from the many available?
I forgot to mention that the course includes supply of glider and harness (helmet too, but I already bought mine). During the second stage of training, which focused on landing on a predetermined spot, I used an Independence Zippy EN-A glider. Now in the third stage I am using a Skywalk Tequila 2, EN-B low. Both belonged to the school. Yesterday I did two hour-long flights, big ears, top landing, and full accelerator.
Person B said that the difference between the wings he uses for classes (Skywalk) and those he recommends for novice pilots (Gin) is a coincidence: two former students who had bought Skywalk Tequila were moving to more advanced gliders, he knew the students and the gliders well and bought them second-hand for instruction, and no Gin Atlas are now on the second-hand market.
