I'm an adult skater (5'7", 160 pounds). I'm completing adult basic and am getting ready to start freestyle lessons and I want to upgrade my blades from wilson excel to an intermediate blade. However, my pro shop has a pair of brand new MK goldstar blades on clearance-- a single new pair that happens to fit my larger boot size. I wouldn't normally consider a blade of this caliber, but the clearance price is actually cheaper than the retail price of intermediate blades. Is there a downside to purchasing them? Most of the arguments I've heard against overbuying blades is that the expense of higher blades was wasted on less advanced skaters. But with price not being a factor, are there reasons someone like me should NOT try the Goldstar? Thanks for your help and advice.
