Why "Baron" if your call is to HB Twr? Its on your plan
and
One might also argue why "POB 2", as that is also generally on your plan]
Because it's in the regs:
Controlled

[aircraft type]
[wake turbulence category if “Super or Heavy”]
[POB] RECEIVED (ATIS identification)
[SQUAWK (SSR code)] [aircraft location] [flight rules, if IFR]
[TO (aerodrome of destination)] REQUESTTAXI [intentions]
Non controlled
(aircraft type) [POB] [IFR (if operating IFR)]
TAXIING (location) FOR (destination or intentions) RUNWAY (number)
