Lo ngumgca we-PE oLukiweyo o-4 kunye no-8 oLukiweyo kunye ne-100m epakishwe ngamadyungudyungu eyahlukileyo.Imibala i-monochromatic kwaye inemibala.Amandla aphezulu kakhulu-nge-diameter nganye.Okumangalisayo okubhityileyo kunye novakalelo oluphezulu lokubala lokubala ukujikeleza kunye nokuqina.Uxhathisa "ukumba ngaphakathi" kwi-reel.
I-1, iteknoloji ye-angle ebanzi ebanzi - umgca ogudileyo ophezulu.
2, Ukuphuculwa kokukhawuleza kombala.
3, Ukuphosa okude kwaye ngokukhawuleza - kugudileyo kunangaphambili.
I-4, ubuntununtunu obukhulu - ukuziva kwangoko kwisakhiwo kunye nogwayimbo.
I-5, amandla akhethekileyo kunye nokuqina.
