Don't pick a different starter because ICs have a big advantage in the ICs-G&W match-up, watch some RECENT (within two years) ICs-G&W sets, blizzard chaser is too good, practice desyncs and CGing G&W
Since FD is usually the best stage for ICs, they are rarely able to play on it because most opponents auto-ban it against them. Thus, most ICs matches are played on SV and BF. If a tournament has five (or three) starter stages you can guarantee that you'll play on either FD, SV, or BF by striking the other stages. Even if you lose a game, (your opponent can't ban all three stages) you can still play on one of the three. You should definitely practice on all stages, but SV and BF are the stages that you'll probably play on the most.
