big time
I had a Jr T 99, 00 and an 01 did not think a 20 would make a difference. I went to a monster in 02 and now have a 03 sup T and I could tell first thing. The bike turns faster and stays put, thats the biggest thing. The fork does not wonder. I take turs much faster with a 20. The brake work better. I dont know if you have disk now but if you do. You know when you turn sometimes you get thet disk scrape for a secont or two then it goes away, that is the fork twisting. I do not get that with the 20mm. I have a DJ3 on one bike with a 9mm qr and will replace it soon with a Dj1 so I get the 20mm. I do recoment the sup T but Answer makes a nice fork (although I have never had one) also Fox has a big fork comming out, that should be nice. The 888 is nice but with the extra inch and crown it is almost 2 inches taller might chopper your bike.
