I have a small amount of money to spend and I am prepared to invest in a HIGH RISK investment. I don't mind about the spread so penny shares are my main focus. Has anybody got any tips?

I've got relatively large stakes in the following (not mega high risk but potential for massive returns) it's worth checking them out:

PRO (awaiting news on G5)
RTD (awaiting next large contract/upbeat trading statement)
GXN (awaiting good profits from Pipex takeover)
PTS (awating next statement in next couple of weeks - good chart signals)
SGD (steady growth, should go on and on)
COH (taking over Poland and Czech Republic with their outlets - looking good)
