I used to swap between drive in winter and pro in summer. I always wait till they have an offer on so you get 6 boxes for price of 5. Makes them £8.72 or £18.73 a box.Your probably right on that, out of interest which Vice ball do you use and what's the cost, I keep getting ads come up on my social media and they do look intriguing
But now I’ve settled on the tour which is £11.73 a box.
