Lessons learned the hard way

Having been riding SS for about 4 years (Terrible FG rider, just can't get cosy with it, no matter how hard I try) I wanted to ask if there are any components that people feel particularly negative about? What should you not buy, no matter how convienient?
When I got my bike together I cut a couple of corners. It started as a cheap project bike, but now obsesses my day dreams!
Aaany way, having had a heart stopping moment as my cheap as you like Dia-thingy freewheel split into my spokes, and dropped all power as I rode onto a fast moving St.Margets round-a-bout I wish I'd known better.
So, Frames, Moving bits, bars, kit, clothes and just about everything in consideration, what should be avoided?

PS. I'd like to put a word in for my LSB (Moore bros in Isleworth) who fixed me up with some good mid priced kit and a sugary Cup'o'tea for a very-shakey and bruised rider. There's a SS rider in every good shop.

htfu grow some balls and ride fixed. That said, avoid anything with the words unipack on it, or that seems too cheap to be good, it is.

I Know!
It's not fear thing, Christ I've tried, It's a talent thing. I think I sit back too far or something.Just keep ballsing it up.

Avoid roadies. They are scum. Other than that, embrace the lowest of the lo-pro..
