Space isn't an issue. Yeah I agree with you crossi, Gold Willow looks to be a more 'wow piece' out of them both! Although supercharged isnt fanned & it has a smaller bore size, it does have more than twice of the amount of shots as gold willow and it's quite a rapid cake unlike Gold willow.
Also in the display there will be Hercules, 2x ThunderKings, Toxic Warlord, Moving Targets, 2x King Cobra or 2x Starring, & War Hawks + maybe a sky thriller.
I might have to leave it to the epic team If I can't decide.
