Mark has the new FT and a Johno SideWheel, his gap is 10mm.
FT MOA2 version - only had it a few weeks but I really like the MOA2 ret - very uncluttered. As Martin said I have just got a Jonno sidewheel and spent Monday getting the ranges on it. I did guestimate the gap when I told Martin 10mm and that was actually from 50 to the end mark. The 50 to 55 gap is actually nearly 7mm (just measured it.
Ignore the initial permanent marker mess - got some vinyl numbers on order......
