LSBF or BPP for F7& F8

Hi guys,
wonder if someone has had any exeperience with LSFB …. i have been with BPP most of the time and I think they are great but i must admit they are very expensive ( especially F7) LSFB seem to have become a key player in a short period of time …. (btw, I’m in london)

Any feedback is highly appreciate and congratulation for all the people who had a pass today and sorry for who hasn’t
xx
