That's true but I think it can improve a kid 10-15% in his skating which is a lot.
The "place in Wilmington" is Cooke's, and it absolutely makes a difference for any kid. He can't skate properly if the skates don't fit him right, and if the blades are the wrong profile for his skating style. It's like trying to golf with your buddy's wife's clubs.
So, whether a kid's a good skater or a bad skater, it will still make him a better skater.
Other place to go to are Zwickers - family run, the old man used to sharpen the skates for the entire NHL, including the officials - and TSR in Salem. Lot of people don't know that TSR stands for Total Skate Repair.
Having good contacts in these three place will be really important as your kid grows up with the game. That means being nice and respecting the knowledge these folks have. Know-it-alls need not bother, they'll see through your BS in a second.
Son gave the 'flat bottom V' sharpening a shot a few years ago and didn't adjust to it. Seemed the edges were more fragile too so more could go wrong with them.
For me as a parent the biggest improvement is to switch-out the blades day one of the skates to better quality steel. For $50 a pair the better steel just holds up better and holds an edge longer needing less sharpening. Pays for itself in a couple months time and lasts longer.
totally agree. My son has been going there for a while. He's an 06 EHF White player so he needs it. Before going there his top speed was 5.2 mph. Now, a solid 5.4.
