The super shots are different in that there is a 'bank' of them on the left hand side - I don't think the top feature is available from them though. Collect 5 'wads' of notes to activate the top Mega Streak - again, not sure if this is the equivalent of Big Money, or if it is a 'proper top'.
The shot banks are also different, in that there's only 'one type of shot' but you can progress up through levels on the right side of the machine. I think there were 4 levels, hitting a feature and rejecting it turns it red. Hit it again and reject it to knock it out completely. Land on an arrow to move up a level.
Like Money Spider, where you exchanged over to the main feature, it stays at that cash position on the trail. Nudging in wins and numbers boosts you up this trail. On 50p play, numbers are doubled. I had a result via this as it gave me bonus nudges which enabled me to nudge in pot, followed by another number (a 4) which gave me the top feature for £50. One complaint though, the top is SO SLOW! I'd say it really did take a full 5 minutes plus to give me the £35! Hoards of 50p wins that then took yonks to be added to the bank. Not that I'm complaining as a top is a top, but come on! I got through 3/4 of a pint before it had got to the end.

There's also a Death or Glory button, which is a bit COB-ish, although when you take it, you get a Yes/No continue type thing, but it's Death/Glory. I took this on my next board (landed on a question mark after a few spins, nothing else to collect) and it said 'Press Me' and lit the cancel button. This enabled me to easily select 'Glory' which gave me a shot at the top values (within the Mega Streak pot) which gave me £15 and a chance at another shot - that one missed. So, made about £50 overall, which wasn't bad at all for a new machine.
Knowing the one other Reflex I've played (JJ) I guess that if caught at the right time, this could go huge?!
