How big is the effect of a golf stick for an amateur

Hi guys,, just a random question popped in my head.

Let's just say that your average score is around 85-95.

What score do you think you will get if you play using your friend's set of club? 

Different driver, wood, hybrid, iron, wedge, and putter.

I think it depends on how proficient is your swing and how much different is your friend's club to yours. It's hard to say if no specs of yours and his to compare.

Below 100

It will get worse if your friend's clubs have different shafts especially different flex and weight.  Suppose you are a regular flex guy with 50g shaft.  Your friend use a 65g shaft with stiff flex.  You will loose distance because your friend's shaft is heavier and stiffer.  

If your friend is Tiger Woods.  Good luck hitting his iron.

Not forgetting his 120g steel tipped driver shaft.

I topped the first few balls using others clubs. Weight and feelings are totally different.
