Also putting down organic matter is bad advice as this will just build up a

If your lawn is small you can buy(argos)spiked shoes that fit over your
normal shoes they are relativly cheap .
Wouldnt worry too much with the sand idea unless you have severe drainage
problems.
Failing that ask your local groundsman if he will spike it for you.
Good luck

Pogo stick with the rubber bit taken off? :-)

I've only ever seen hollow tining on golf greens. Never on tees or
anywhere else so unless there's some drainage problem I'm not really
sure it does an awful lot of good.
