Many thanks for detailed experiences of both your son and daughter.
I only started looking into profile differences once I had the blades
scarletskater.wordpress.com/2017/06/02/blade-profiles/ was the most helpful of them all talking about various bits and probably confused me the most.
I am glad they adapted quickly. I am keeping fingers crossed. My daughter likes Blue and for that reason I picked the blades that I did as they were Icy Blue. She doesn't know that - and she chose the same when looking on Paramount site the other day
Yes the blades to get dents and scratches - my daughter did that to MK Pro in early days of her axel back in the day - these would be more noticeable. My daugther's main coach sharpens for most skaters at Romford and his sharpening jig is compatible as his sons use Paramount too
