This is excellent info. I was concerned about the brakes but after what you are all saying it sounds like it isn't an issue.
I was unaware of this WR mod, and considering how simple/cheap it can be done I don't know why everyone goes with the WP conversion.
Thanks all for your help! Saved me from paying extortionist prices for the otr kit, or messing around with 990 forks!

Time to start sourcing parts!
