I've made this one twice, the second one was better than the first. I made it with:
1 Can Coopers IPA
2 LBS Light DME
2/3LBS Corn Sugar
.5oz Liberty for 20 min
.5oz Liberty for 1min
.5oz Fuggles for 1 min
8oz Maltodextrine
Kit Yeast
Method:
Boil 2 gallons of water, added the Maltodextrine and cor sugar; added .5oz o Liberty for 20 minutes. At 1 minute added the .5oz Liberty and .5oz Fuggles, removed from heat, mixed in the kit and the DME. Cooled and added to 4 gallons of cold water to make 6 gallons total.
In all honesty, the weird combination of hops was due to the fact that they were what I had on hand!

I used some corn sugar because I had read somewhere that Cooper's yeasts are formulated to work with at least a small amount of sugar.
It wasn't bad, buut the next time I'll use more English hops to finish, or maybe some to dry hop.
I enjoy Cooper's kits, mainly due to the time constraints I'm under these days - taking an entire day to brew a batch of all-grain isn't possible right now.
Good luck with your IPA - let us know how it came out!
