I love my FR Shock. I use it all the time now for ~300 foot tunnel shots..e.g. on this hole I get birdy putts a lot now.
Eventually I'll be able to reach this with a mid range, but for now the Shock I can throw with just a bit of power and get all the way down this gauntlet, and if I turn a bit that is OK because there is some room to the right.
Some day I'll loose this disc and be paying crazy prices for one :P
