As a previous employee of Cap, I know that T6, which is in TS part of Cap, is equivalent to C3 in the CS part of Cap.A C3 is a senior consultant. Supposedly, CS employees (business consultants) are better remunerated than TS employees (IT consultants). I think the highest salary I have ever heard of for a C3 in CS is 80K (the range is probably 55K-80K) so in my opinion you are the Don for securing such a salary in TS.
