Thanks, went ahead and ordered one. Are you using that many shims for top end or your altitude. I have a MTX at low elavation so no need for top end speed just power at low and mid.
The more shims the quicker the response is, the 8FP are heavy and smaller shims make them a little lazy in mid but more on top. So yes it is a preference thing depending on where you want your power.
