I've always carried my bag and am 31 yrs old but have always suffered from back pain due to my past sporting career. I have always enjoyed carrying my bag when I play but now find that I suffer a day or two after each round of golf with more back pain. I know carrying is not the sole reason for the pain (Twisting in spine during swing, shoe selection, uneven playing surfaces, etc also contribute somewhat). My goal has always been to carry my bag until I hit 40 yrs old but I'm seriously thinking of making the switch soon to make life easier on me.

Just wondering if there are any other Golfers in my age range who have converted to pushing their bag permanently?

I've been looking into push carts and see that Sun Mountain and Clic Gear seem to be the most highly praised. Wondering what the difference is between a 3-wheel and 4-wheel cart is? I really hope I don't need to buy one with a seat just yet! Any insight would be great. Thanks
