In the end I found it easy to time using the red lines. The pattern of red red, long spin, red red etc. got me into a rhythm of when the fast reel was right, and I stopped it when my mental rhythm said NOW combined with watching the other two reels. I got a feel for the patterns so I knew when the setup was coming round. I also remember learning setups that worked on the chipped version, that came round within the time limit. Same as Spin On It, nudging in the best win was not always the best play (I particularly remember some lovely cherry setups on SoI where pot or hidden was there for 5 blasts, and we reckoned the machine looked at nearby wins when deciding where to put the nudge exchanges so a nearby win of £1.20-£3ish could make it put an X by a lower win that was also there for the forward/back/forward trap on a SPIN number, and even if no better win, an exchange for 5-6 nudges was often worth using to bring down the next matching symbol on one reel for a better Super Hold / Red For Reel / Reel Blasts setup).
