Second that. Pulled my Grubbs All+ from the cupboard after a 15 years pause and it felt as if nothing happened (rubbers tho worn out.. new tensors were fun)Yeah I'm with Loopadoop here.
My Stiga Clipper is probably 6-7 years old. If it has changed at all, then the difference is so small I can't tell the difference. So then I must ask if it matters.
Unless you plan on going pro, I wouldn't worry about it. A bat can last you pretty much forever or as long as you want it to.
Does the paddle ever deteriorate? Or should you only buy a new one when you're upgrading?
