I saw in the sys.txt that comes with the downloads there is this ( profile_name=nng-igo-tmc-igoworld is used in that one) :

Spoiler: sys.txt
[tmc-http]
enabled=1
;profile_name="nng-igo-tmc-jci"
;profile_name="nng-igo-tmc-iphone"
;profile_name=nng-igo-tmc-beckerfull
profile_name=nng-igo-tmc-igoworld


I use in my sys.txt :
profile_name="nng-igo-tmc-iphone"

Question is which one is better ?
