LS 2 and 2.1 radius

[aal 3]

I understand the tuuk lightspeed 2.1 is a longer blade than the 2, but is the radius any different?

LS2.1 = 11'

LS2 = 9'

Thanks. Another question: Is changing out the blades something a shop needs to do, or can I, with no experience, do this myself?

Buy them from your shop. They'll replace them and sharpen them for you too.

If you just make the switch, go with the shop and never worry about it. You can also do it yourself if you want to swap around. I can't remember the socket size (11/32" sounds right for some reason), but a rubber mallot and the correct socket are the two required/suggested tools.
