Well in the program I was in it seemed like I had a different instructor everytime... I used a 210 sabre 2 for a good portion of the jumps and landed it perfectly almost every time. I guess I'm just not sure when is the appropriate time to move on if you have mastered landing and controlling a certain kind. Right now I feel comfortable using the 190 but not near like I could the 210. However, it just seems kind of dumb to buy a 190 if i'm going to have it completely down in another 10-15 jumps. I just don't know much and don't want to assume things, so I was trying to find out what people experienced themselves I guess, rather than advice. "I didn't know they gave out rings at the holocaust"
