Well, I can't compare it with (old) Wee, as I've never had one. The only thing I could speak of was a difference without and with fork brace on my Glee. I also don't know if it's better or worse or the same compared with other brands but I guess they all do the same job.
I got my Glee in the beginning of the winter. That fact is important as in this time of the year, here in south, we have mild temperatures but we suffer a lot with a wind. It's not constant, strong wind. It's more like little wind with huge guts, so very, very unpredictable. It doesn't blow every day but can be very dangerous. Also, it changes direction almost every day. Forecast for today is N, tomorrow NE, the day after S and the next day SW. During a ride you feel strong hits and if you're not alert, you may go down. That is one point where my Glee has transformed. For example, this morning riding 120 km/h on the entrance of the city where I work (area known for big wind guts) at one moment I got hit by instant strong wind gut from half-left. Without the brace, in that situation my Glee would loose its trajectory in about 1 meter being pushed to the right. I was not expecting the "hit" that strong this morning. But with the brace I took strong hit on my body (I'm 6"2.5) but my Glee lost its trajectory not more then 15-20 cm to the right. That's huge difference for me.
Other thing is, on my everyday use I ride a mixture of different roads but almost never freeways. I go to freeway just from time to time but that's very rare. So, on that mixture of roads I have a lot of tight corners, crossroads, junctions... a bit of everything. And that's exactly where I feel the difference, especially if road surface is in poor condition. I feel now much safer in corners as my Glee has perfect trajectory. before it was a bit wobbly so I had to constantly control and correct the trajectory along the corner. I have no idea yet if there was any difference on the freeway.
This morning, after resetting the brace to have the gap as Cosmo says, my suspension works as it should, no problem at all.
I'd still like if we could get to a torque value for outer bolts. That would make fitting dead easy.
I'm in no way professional tester, nor specialist, nor racer. What I wrote about Cosmo's Fork Brace in last few days is purely what I feel during the ride, the changes I experienced. I know that this can be purely subjective and it probably is. Someone else may not feel the same but I'd buy it again without hesitation.
