Hammers,
would suggest you go live asap. Only bet so small it is unemotional if you lose. The only way to know if you can make it work is to put real money on the line.

As for each way betting. It's a personal/emotional thing. Betting each way your runs of outs will be smaller (you lose less) but when you win you win less.

The maths people tell me only bet each way in 8-9 horse fields witha bookmaker at prices of 4-1 and under, 2-1 and less is even better.

That ought to stir a few people up!
