Ganacsiyo badan ayaa doorbida xaqiiqda ah in macnihiisu yahay 600 ay tahay isbadal aad u badan. Sidaa darteed aloy-ka waxaa loo isticmaalaa dhowr warshadood oo muhiim ah qaabab kala duwan oo ay ka mid yihiin kuwa caanka ah ee aan caadiga ahayn 600 tuubada. Dhismaha tuubooyinkan ayaa laga yaabaa in laga dhigo ama ay noqon karaan kuwo aan kala go 'lahayn. Waxaa jira faa iidooyin lagu isticmaalo labadaba. Loogu talagalay E.G. Doorbidida ah in lagu xusho 600 oo tuubbada weldelka ah, ayaa ah codsiyada ay dhaqaalaheedu door muhiim ah ka ciyaaraan. In kasta oo laga raqiisan yahay midka aan toln lahayn, tuubooyinkani waxay leeyihiin isku-dhafan dhaadheer, oo u nugul u noqon kara isqarxinta isqargalinta - haddii si qaldan looga baaraandego. Muuqaal ahaan, halkaas oo uu iibku u baahan yahay qaabka ugu sarreeya ee caabbinta xasaasiga ah iyo awoodda looga hortago cadaadis, oo aan la taaban karin 600 tuubbada xariifka ah waa ikhtiyaarka ugu fiican.
