The problem with the E2/10 or E2/25 is they are not consistent. The F2A/25 or 10 will be quick …ish in anything bar a gale. Same for the B25/8. The E2/10 (and the same for the 25 when the road works are done) can be lightening fast (I did a 20 on there this year) but on what looks (until you get out there 
) a similar day it can be a minute or more slower. In addition the E2 is quick with an E/N/NE wind but slow with a SW…guess which is the UK prevailing wind direction
