before buying Ohlins forks, you should look into replacing the internals...springs, valves, etc. You may purchase Ohlin's internals w/o buying the whole forks.
Aside from Ohlins, you should look at Race Tech...they have similar high quality internal components.
And yes, have the forks (and/or shock) set for your weight, riding style, etc. will make a noticeable difference in the way the bike rides, handles, etc.
Good luck!

replacing the internals won't help him if he has a scratch on the fork tubes causing a leak.

true, but he could buy a cheap set of stock legs & new internals, and still spend less than buying Ohlins forks.
