How Bigs your Rod ?

[TSPS]

I've been fishing a 9' Starrod 1-4oz med/hvy with a abu 7000c3 ,I use 30lb fireline. This set up has worked pretty well for me however I still cant reach the middle of the canal even useing the pedulem cast.
Last week I saw alot of fish in the middle of the canal under the RR Bridge.So I went out and bought a 10' Tsunami 4-6oz hvy hopeing this might give me the extra distance. However if it's too long you'll the bank behind you , too short and you get no distance .

So the question is what size rod is best for the cannal ? ( I'm useing plugs )


Thanks
