I agree about home advantage, over the years top racetracks like Somerset, Scunny and P'boro have all provided good home advantage when the home teams have been strong. As the season progresses this team will get better and better, particularly at home.
Just important to get off the mark tonight, any kind of win will do. There are no trophies handed out for tonking teams in April. This is a potential banana skin with Somerset likely to be right at home in their big, fast surroundings this evening.
I personally think he grades to much, and it can be to the detriment of the racing. Every four heats should be plenty. Have a slightly longer one after heat 8 so people can get a cup of tea and have a pee, but no longer than fifteen minutes. Get the two minutes on promptly for the other heats and the meetings won't drag on unless of course the sun delays the start which unfortunately nothing can be done about.
