I went back to trad after about 5 months of WFP.
I weighed up the pro's and cons of both and found that trad suited my round better.
When i pop on this site now, i'll see loads of posts about fixing problems with hoses, tanks, filters, batteries, freezing etc.
Too much potential time wasting/ expensive hassle in my opinion.
As for the safety aspect of ladders, i have worked in all this icy weather with spikes and ladda limpets fitted.
Even on the slippiest decking i've felt 100% secure.
Again, only my opinion but i've never regretted going back to trad.
When i weighed up the overheads involved with wfp and now my only regular investment is fairy liquid and rubber blades, it made perfect sense for me.
