Charles:
Here's my 2 cents on handlaying track.
I did hand lay some of my HO track (including a turnout or two) on my first layout 30+ years ago. The track and turnouts functioned fine and looked fine - but took a LOT of time and work to make.
Well I sold or gave away that layout, and a few years later started another using all store-bought track (Atlas nickle silver code 100 flex track, and at the time I bought about 20 Model Power electric turnouts - #4s at $4.50 each - that had nickle silver rails.) I still have, use and reuse this track and these turnouts on this layout.
Why did I change from hand laid to purchased track? The time and work of handlaying was just too much TIME (I would rather run trains than hand lay track) and WORK (I wouldn't enjoy it), and here's another reason: model railroads are REPRESENTATIVE of real trains, so then so what if the spike heads were scale-wise too large and the rail was about a scale 4" too high? I could live with it. Also, the Atlas flex track is very easy to work with and makes laying track seem lightning-fast compared to hand layed.
However, having said all that, if you want hand-layed track - go for it. And laying track by hand might be easier today if you use Fastracks (spelling?) jigs and templates.
Lastly, does hand layed track function better than commercial track? I don't think so because I have an L shaped loop with 22" radius curves, Atlas 100 flex track, that I sometimes run my 65-car train on backwards (shoving with two engines) with zero derailments. [Why do this? Just because I can.
] As info, of the cars on the train 85% have plastic wheels and the rest have metal wheels. And when running backwards the train goes facing-point through an old Model Power curve-on-curve turnout.
Enjoy your new model railroad.
