Rotor Phasing

I had someone tell me the rough spot I'm feeling around 2500-3000 rpm is because the advance rate is coming inn too quickly.
Right now with 16 degrees of mechanical advance and the initial timing being at 18 degrees and the total timing being at 34 degrees with the springs that are in the distributor that advance starts to come in around 1200 rpm and is all in by 2400-2500 rpm.
This is on a 300hp crate 360 mgnum with an advertised compression ratio of 9:0.1 running premium 91 octane eathanol free fuel in a 91 w150 short bed 4x4 truck with a 4 inch suspension lift and 33 inch tires with 4.56 gears.
Is that too quick of an advance rate for this combination?
I forgot to add I'm also at 3200 feet above sea level, I know that has an affect on timing and advance rate.
The person i was talking too reccomended slowing the advance rate down to around 3000-3200 rpm.
My thought on it was with the lower compression ratio and the premium fuel and the higher elevation with lower 4.56 gears that all in by 2400-2500 shouldn't really be an issue.
But then again I haven't really played with different spring combo's and don't know everything when it comes to tuning a distributor and setting up the curve.
