Just a quick tip that (I think?) I heard Joe Rstrom point out during Worlds:
If you find yourself icing your hot balls for play, it’s best to take them out of the ice bath perhaps thirty seconds before you’re going to put them into play. Idea being that a completely frozen ball is not exactly the best thing to hit at full force, and it won’t respond how you expect it to (really, it could just break apart. Let’s be honest).
Editor’s Note: A reader commented below that the most current form of the Fixcraft Hot Balls are not meant to be iced at all, but kept only in water. The more you know!
Something else that he said in passing (he’s so full of wisdom) is that the process of evaporation can cool the ball to the just-right temperature more often than not, so dunking a ball in an ice bath and then leaving it out on the bench might be your best bet to get them to the right temperature for play. Naturally, you’d want to do this to a few balls for the course of a game at once (so you can just throw another out when the first gets too gooey).
I haven’t necessarily tried the evaporation method yet, as it’s been too cold to worry about overheating orange balls, but I have high hopes.
Any other tips out there?
