You’ll definitely want to go with a front drag. It does take some getting used to for some anglers to control a front drag as opposed to the easier rear drag, but the washer system on the Symetres is a good one.
Years ago when I worked for an outdoor company, the Shimano rep came in and talked with us and went thru the reels with us, showing how the drag system worked. The Shimanos were impressive. And if I’m not mistaken, I do believe what was previously mentioned here is true in that the front drag will give you more area, which will provide a better, more solid drag.
Plus, keep in mind, with the front drag, the drag system is right near where it’s needed: the spool. With the rear drag, it goes all the way thru the reel. Since I went to front drags 17-18 years ago, I’ve never looked back.
