That's a very general question and anything is possible. Montauk is a big place with lots of different types of fishing conditions at any given time. Sometimes the fish are right at your feet, sometimes you really have to work for them.
JakeF you are not wrong! I meant to make a little general because I am not in the elite of fishing. I have a really tight budget being a working student! But I wanted to see from the experienced fisherman here if they had any times they've used and succeeded with a 7footer or have not. I appreciate your reply though thanks!
I personally have never used a 7' rod at Montauk, but I can tell you that there have been a number of times that I could have gotten by with that while fishing there. Make do with what you have, but be careful and use your head.
