FICC Sales Analyst 2 to Trading Associate 1

I'm currently a second year analyst in FICC sales (mostly swaps/rates focused) at a BB and am contemplating a move to one of our trading desks as an associate 1.  

I am mostly considering the US govies trading desk or swaps desk since they are closely related to my current role (vol desk has also crossed my mind but our vol traders seem to get wrecked during market hours and are always frantic).

I think trading would be awesome but one of my trader friends told me it is extremely difficult to move to a good role at a HF unless you are a relatively senior trader and bringing in PnL / managing a portfolio. I don't know if I want to stick around at my current firm for another 4-5 years before being able to find a good exit opp.

Any thoughts on upsides of a govies desk vs swaps desk and how difficult it really is to land a good exit role from a BB bank as a mid-junior level trader?
