We have a pretty bad history with pairs of best friends who apply together, rise up the ranks together, and then leave together. Their primary allegiance (understandably) is to each other, not to the betterment of the clan. I get it. But it's risky.
At the same time, two best friends can do a lot of great things together. If you two were to be involved with managing part of our events, for instance, the likelihood that you do a good job of it is much higher because you know how to communicate and share tasks. Similarly, theoretically you will be better at teaming up in clanwars etc.
So there are pros and cons to accepting two best friends together, and the risk of consequent disruption is high.
In any case, like Ferrari said, the trainee rank is designed to filter out the suitable from the unsuitable. I see no harm in letting you guys in on the trial logic, and I hope to see you emboldening the clan in the ways you purport to have tried to do in SS.
The application is a little soon after your departure from SS, but this decision is logically tied to the decision of Leder, who was there for quite some time. It seems to me the primary motivation for your fast application is not opportunistic clanhopping, but rather taking your VC:MP journey alongside your friend. Your secondary motivation(s) might be opportunism, I don't know, but it's not the most salient issue in this matter.
Voting trainee for you and Leder.
