Its not a steel shaft its a graphite stiff shaft. Like i said it wasnt stiff enough for me im 18 and have had it for nearlly 2 years so dont know could always buy and then sell if no good ... Bargin price!
At 15, I would suggest that a Aldila Proto VS in stiff is a tad stiff, sorry if that seems a bit harsh in the for sale section, but I would never describe that shaft as being "soft" enough to be called regular!
I feel like all aldila shafts are not as still as pro force or matrix. I also have had stiff shafts since i started playing and that was age 14 but each to there own no probs if doesnt sell.
