You all know how I gush about the Inertia, and I'll go ahead and give it more praise right now. I threw it FH only today, and it amazed me in it's versatility. It was hard to get used to, but I had several throws that were clean as a whistle and this disc performed beautifully.
Anyone thinking you need a Motion or Resistor type disc to play FH is mistaken. The Inertia was straight buttah when it had to be. Obviously an overstable disc is great when needed (either BH, or FH) but it's not always necessary. On one of the holes I threw my longest throw that I can remember. It was from a standstill, and I found my form for that instant and it went laser straight...so clean and pure. I estimate it was about a 300' throw. There's something about the grip that fits my hand perfectly both BH and FH.
This disc does it all. I never thought I'd replace the Amp, but the Inertia has pretty much kicked it out for good.
