Carbon tiller

Hi All! Europeans RDL in Athens are done, and I've got a boat after that event. Aussie 210... in very good condition. Now I have everything, including tiller and tiller extension and now I'm stuck with 1 question : is better to use carbon tiller (flat) or continue sailing with a stock one ( round one)? IMHO I prefer to get carbon one because I can make my traveller tighter than I can do it now and probably on tacks my double blocks will not stuck because of form of tiller

P.s : if somebody...
