SidersBest: So that you don't waste useful hits on paid for balls.
Putts don't decrease the life of paid for balls (don't count as hits on).
I'd also advise against using the free balls for any sort of practice. They react too differently compared to, for want of a better word, proper balls to allow you to learn much from using them.
I play with the L33 Callaway ball, have done for years. Through it being called Tour iS, Hex Chrome and now Chrome Soft, basically the same ball with a different name. In WGT land anyway. And I use that same ball for almost every single shot I take here, the exception being for a fun alt shot round when I sometimes use the Korbel ball. By far the best novelty ball in my opinion.
My point is, there is no point practicing if you are using different equipment to what you usually play with. Find a ball you like and can afford and stick with it, ideally for every round.
As to the new tier blues, I can sympathise with that. A new tier and green speed can really set your game back. You will get used to the greens though, it may take a while but you'll get the feel back and will wonder why you had any trouble in the first place. Then you'll jump to the next tier and it'll start again.
Hang in there, it's worth it. I prefer faster greens as I'm sure many do. Not those silly 16+ ones Icon likes to throw at us now and then but champ speed is great.
If you find yourself getting really fed up then I'd advise you to play some alt shot with 3 friends. Just forget about winning or losing and have a laugh. Alt is by far the best time you can have here.
