Dif between OEM handle and clamps Vs aftermarket Protaper

Hello Guys, I just wonder what is the difference on performance if I use a Renthal or protaper fat handle bar with the clamp vs the original that the bike came with? I don't use the bike for racing just some off road on trails not tracks and to conmute to work during the summer time. Just wants to see if it is worth to spend the money on this items or may be use it towards some other upgrade. right now is bone stock, the first mod I am going to do is the uncork kit from Honda, right now I am leaving on Vacation next week until next year to a nice sunny beach down south! the heat is going to be over 38 celcius (like BURP city) LOL, that means I am going to be drinking a lot of beer!! I will drink some on your names here guys!
Thanks for the reply on this in advance

Nobody needs different bars (I am having an exceptionally rare 'honest' moment now, pls note) but they just look the balls, so of course I also have one - a bar I mean, just in case you want to ricochet a nasty/silly/funny remark about my incomplete tackle
Actually that's not totally true. They flex less, and they will bend less quick if you park it horizontally, which means (for me) a more reliable setup, and for racers fractionally more control. Also they should vibrate less, but we're now talking about minute differences here.
Compared to all the other stuff I've added this item is cheap, so I threw it on without even thinking.
Now you ask which one of the fatties is best? Just about exactly the same, unless one of them can be had for a bargain. So, the correct answer is: the one you like best!
Beer? On what beach? Surinam, some fancy isle, or where? Bugger the beer then, I'd rather worry about the way it is served. Shortness of skirt, shape of legs, the top-heaviness which may cause the poor girl to topple over, that kinda thing. Details pal, details, ever so important, they can make a lousy beer worth ordering again!
Have a good un, I'm on my way soon too

you can write a book Burp

yeah, Riko is right Burp, I wonder did you take politics at school!? LOL!!! you are right about the details on the beer I prefer a bikini than the skirt but better not get into this details here
