I bought a GHL5 earlier this year and it is an excellent blade, one of my regular playing partners who uses a Bty FZD salc tried it and was annoyingly good with it.
However, coming from the 7 ply HL3 it was still a bit too immediate for me (outer carbon doesn't seem to suit my technique, and HL5 wasn't quite what I was looking for either), so I have recently bought a W968 provincial (wish I'd just gone for it earlier as SFF_lib had suggested, oops) which even after very limited use appears to be the perfect fit for me with more dwell and flexibility.
So you may find the GHL5 suits you slightly better. And without wanting to seem pushy. . . I think I will be looking to sell my GHL5 if you're interested. . .
