I would consider myself a golf beginner and my favorite part of the game is watching myself improve with each and every club. I have a set of clubs my dad gave me probably eight years ago and have just now seriously started playing them this season. I have continued to use the irons from the set but have upgraded the putter to a cleveland mallet putter which i feel as if i have great control over but need to re grip. The driver i use is some beat up wal mart driver that i got for ten dollars at a garage sale. Just recently i have stopped slicing on every shot and hit about a constant 250 or more yard drive. Also in my bag i have a sand wedge and hybrid that arent name brands passed down from my grandfather but i can hit both pretty consistently. My irons i continue to see improvement with, they are a set of tour select clubs(made by northwestern) they are very cheap clubs. My question is that although i can hit these clubs decent how much improvement will a new set of clubs bring? The picture included is what the original set looked like.
