Defo Sam Ian's lap is on my list - that lap on a TZ250A-the last of the quick reverse cylinder 250's was right out there -remember watching from Signpost, another epic less known 2-stroke memory is Charlie Williams's TZ350 112.8mph lap in the 1979 Classic TT finishing 3rd behind Mike Hailwood and Alex George - a truly outstanding lap of the course without any of the later "improvements" and a road surface much different to what we have today...I was on the scoreboards with Scouts that year.... and following on from BSA499's words - yes Sir all of that, my 92 MGP Junior replica is sat in similar place, watching and competing in early morning practice was the most surreal tactile atmospheric experience myself and my crew ever got involved in outside of the actual race.
