Went out in a Schick cam'd 172 the other day, most impressed and I had a nice big smile on my face.

the one and only, most impressed mate.
The 'best' cam for you will entirely depend on what your trying to achieve and your engine spec. On a stock type engine be best cam will be one which peaks power at just before 6800rpm (as the stock ecu retards the vvt then and power drops off like a stone), but builds MASSIVE torque over the stock engine.
There will be a point in camshaft profile where you cannot build both power and torque at the same time, and you will start loosing in one area to gain in another. Troughs and peaks are natural in the power production of engines.
We will have a new cam profile ready shortly for the nearer stock type engine that will have fantastic torque gains whilst peaking at 6800rpm, just before vvt is dephased. This will ensure that the profile is configured to make the best torque possible as peak power positioning is through design, not ECU vvt reduction.
A large amount of time has been spent to ensure that the valvtrain harmonics are better than stock, meaning that even with the rapid valve opening acceleration rates, valve velocities and jerk factors are even and smooth. This will result in zero valve float and bounce and no resonant frequencies building in the stock valve springs, since they are only single items.
With the current profile, peak torque figures of 180lbs.ft and increases of 29% can be seen in an even torque spreak across the graph from as low as 3500rpm. The main thing you need to concentrate on with torque enhancement is area under the graph, and number averages. Peak numbers on a torque graph mean very little in the overall driving experience.
