LC: Beat: My clubs suck. w/ question

[SoloAJ]

Not only are my clubs slightly short for me AND about 7 years old, but I only today found out that they are also KMart clubs.

I was thinking of getting at least a new set of irons for $200 or so. Maybe something like old WilsonStaff Di5s ( http://www.golfdiscount.com/Detail.bok?id=2480 )

I assume this is worth the upgrade, just to get rid of 7 year old KMart clubs. But is there a set distance prediction in terms of how many yards I'll pick up on a given club?

Reminder: I'm a 100ish golfer so maybe having KMart clubs doesn't matter?
