You probably use the rod to hop or jig the bait more than the reel so I doubt it will affect that at all but where the faster retrieve pays off is that dead/slack water away from cover and back to the boat. It will help you get the bait back in and make another cast. Also helps when taking up slack on a hookset. All in all I truly feel like the 8.1's I use on bottom techniques fit me better and the way I choose to fish.
Realistically you will not see a huge difference from 7.1 to 7.3 if IPT is close. Also IPT is the biggest factor as well.
The dream is free, the hustle is sold separately.
