Perhaps leather and scrim should make a comeback prior to using rubber? perhaps Level 1 then say in 6 months after an assesment by the Master of the wheel tappers and shunters club level 2 could be trialled but only when under direct supervision of both great grandparents and their respective parents.
Its should not make that much difference what someone uses...why is it punching your buttons so much?
Tommorow I shall go out and clean my allotted number of houses and I will achieve my target amount of money..come wednesday I will be having a couple of days in a nice hotel in Amsterdam being a tourist...and whether you, I, the Turkish guy who gives me evils when we both clean houses in the same street use trad, wfp , the tops of their head who cares.
Clean the window, clean the house get paid move on repeat on next cycle.
It's just window cleaning...nothing more...the important bit is being a good business.
Cheers
Dave.
