thanks Gary , very clear
now a personal problem , due to knee operation I have trouble kneeling , yesterday it didn't work out
so I think it won't be better next week
I know you are allowed to take the kneelers standing (talked to Pete Sparkes about that) but can you take the supported kneelers as supported standing if there is a possibility to use the support while standing ?
another possibility is reversed kneeling but I find it hard to do , not very steady ...
