The biggest problem is you don't do enough trad cleaning. Imagine how good you would be if you put only half the time, effort, practice, research & trials into trad as you have done with wfp!!
The truth is, trad takes just as much as wfp to perfect. There's technique, equipment, solution & solution ratios- which may change depending on weather conditions etc. As with wfp, you'll only get better by experience, knowing which tools to use & when etc.
But, as with wfp, everyone has a different oppinion!
I think you would be very supprised if you went out with a top, experienced trad cleaner for a day! You'd soon realise how much crap is talked on here!
If you're profficient at both then you really have no limits, swap methods to your advantage.
So, if you want my advice, practice, practice, practice, there are loads of ways you can improve & perfect your trad techniques giving you top results in far less time.
