I haven't been here long, but I have been quite taken aback by this wfp versus trad thing. I have 13 years experience trad, and 2 years wfp. A good friend of mine got me into the wfp thing. While it has advantages, it has disadvantages. I feel the wfp crew exaggerate the difference, just to get at the trad guys. I feel wfp is overrated here, if your a quick trad guy there isn't much in it. Factor in the extra cost of wfp, there is little to choose in my opinion.
If you can do both well, your laughing - they both have a place. If I know what I know now though, I don't know I'd have bothered with wfp. I would simply go trad and, target work that suited trad.
In summary, I think what you read here from wfp guys is often due to the fact they are on the wind up, or were slow trad window cleaners. I'm sure wfp suits some rounds more than others, so I'm sure there are a few guys just speaking as they find.
