Been practicing my Rollers and sidearm on and off the last 2months.
I noticed today while practicing my Forehand Roller that I could get to the 300ft.mark at the soccer field with my Champion Monster. All my other Discs were going about 200 -250ft.

It seems like very overstable Discs do good with forehand Rollers
because they do not flip over to the left too quick. The Monster seemed to hold the line so long before it gradually tailed off to the left.
Have others found this out to be true ???

I have a quite similar experience with these OVERHAND rollers....'sidearm' rollers are something totally different. I roll overhand with a vintage FX [pre F=FX]. :p

Monsters are good. I use the Pro Firebirds (post CE, pre Champion plastic) because I never got comfortable with the Monster's lip. But I agree with slo, CE Firebirds are the best. :)

The key is overstable, but not Z-Xtreme, CE Viper, Speed Demon overstable.

I have a heavier "FL" than the FX; it just doesn't "cut" it...*hehheh*. :D
