tossing iron, alot of older model reels that were made in the 90s era were built tough and didnt need backing but were a bit on the heavy side.....if you could find an old LG custom or similar reel like the river runners 1 or 2 model or an old tournament drifter.... they dont require backing either some guys use old mono as backing for those old reels....i think there is a river runner for sale on kijiji for pretty cheap. or you could step it up to the high end reels low number customs as mentioned above like the rsg reels or even an al taylor, you wont find many of those reels around for sale, just gotta keep your eye out and expect to dump a gnote or more on one of those..
goodluck
