I think its all a matter of taste and your goal. If you are into competing in a high level judged event, then you need to get a set of appropriate repops. I have two cars with orig tires, and i don't feel that comfortable driving the darn things, I usually end up with white knuckles and feel every rut in the road. Also being 38 years old and deteriorating adds to a real driving experience.
I drive all my cars and have several sets of TA radials which I interchange. This tire has always performed well and is the accepted standard for the muscle car market. Decent look (yes i agree an original bias ply looks better) great performance, have a size for most applications and reasonably priced...Whats not to like!
