Upon opening the box I recognized how well this fork was built and designed. After installation I was able to tune it and get it going pretty quickly. Very straight forward do anything fork.
Summed up: This fork is well worth the upgrade, you WON"T be disappointed.
Yes, I would recomend this to a friend.

Made a mistake and bought the smaller of the two offerings and even though it's not the extended version, it works just fine with my Vee 4.5's. So I kept it and have had no problems. Bought a 3.8 tire just in case but haven't needed it. Boy! What a difference the shocks make on the hands and wrists! Just be prepared to cut the steering tube. It's really long - even for a 6'3" 200 rider.
